Harrison Ford may be 72-years-old, but he's still airworthy -- even in a 70-year-old plane -- according to experienced pilots and mechanics who have personal knowledge of the actor's aviation skills.

We called around to various pilots who fly vintage aircraft, and several have had first-hand experience with Ford. They say his motor skills are good and he is thorough and professional when it comes to inspecting the planes he flies before takeoff to make sure they're airworthy.

There's no FAA rule that knocks a private pilot out of the air after a certain age, but all pilots over 40 must get evaluated every 2 years for vision, hearing, blood pressure and mental acuity. They also have to prove their flying skills.

Ford has logged 4,000 hours in the air with various aircraft. As for the one that crashed, however, some pilots have reservations, especially when it comes to the engine. The Kinner engine that quit on Harrison "isn't the most reliable," so claims a pilot who is very familiar with the aircraft. But several people we spoke with say the plane in question was well-maintained and "solid."

And the pilots we spoke with all said the proof of Ford's flying abilities were validated on a Venice golf course Thursday ... he laid it down as safely as possible, without an engine.

Gwen Stefani was looking hella good at her son's soccer game Saturday ... and single-handedly blew away the other soccer moms standing within a 100-yard radius.

The 45 year-old No Doubt singer was in Studio City cheering on Kingston while holding onto his younger bro Apollo. It's almost freakish how she doesn't age, especially with 3 kids.

Amal Clooney's students at Columbia are gonna have trouble paying attention to her lectures ... at least if this photo of George Clooney's wife out on the town is any indication.

Amal cruised around the Upper East Side on Friday ... a few hours after it was announced she'd be teaching a course on Human Rights Law at Columbia in the spring.

Justin Bieber now has a new way to impress women ... by dropping thousands of bucks on booze in his never-ending celebration of his birth 21 years ago.

Bieber hit up Ivy Nighclub's Varsity Friday where DJ Khaled was hosting the weekly bash. He dropped $3,600 on Dusse, Dom and Grey Goose ... but it was mainly for the women around him, including model Lira Galore.

And speaking of the women around him, Bieber went to the club just hours after cops were called to his Miami hotel room ... we're told several woman called police after security kicked them out of the room and didn't let them take their cellphones and other personal items.

One thing's for sure, Lindsay Lohan looks way better in a cream colored coat and bell-bottomed black slacks, than jailhouse orange ... which she keeps narrowly dodging.

Lohan was walking around London ... where she's been flying under the radar since an L.A. judge ordered her to perform 125 additional hours of community service.

This is the best we've seen her look in a while -- however, time spent putting together one's outfit and applying one's makeup ... does NOT count as community service.

It's unclear if LiLo's aware of that.

Bobby Brown was the one given a gift on Bobbi Kristina's 22nd birthday ... he was allowed to gather both sides of the family together to celebrate her special day.

Sources close to the family say Bobby and his wife, Alicia Etheredge, were allowed to invite several members of the Brown family to join them, along with the Houstons -- who've been at the hospital every day -- for Bobbi Kristina's birthday vigil.

Tyler Perry and Bobby's brother Tommy were among the family and friends who joined them at Emory University Hospital Wednesday for cake and some semblance of normalcy during this difficult situation.

As you know ... Bobbi Kristina was found submerged in her bathtub on January 31 ... and has been in a medically induced coma and on life support ever since.

Kim Kardashian said hey baby, take a walk on the bright side -- debuting an ultra blonde hairdo in Paris.

Kim and Kanye West walked out of Le Royal Monceau Hotel, and -- it might just be the new 'do -- but she had a disturbingly distant look on her face ... maybe thinking if change is a good thing.

Bad news ladies, Mr. Big from "Sex and the City" is now walking with a big cane.

Chris Noth's been pulling off the sexy distinguished gentleman thing for years -- but Wednesday he was spotted in NYC's East Village with a new prop.

There is only one possible reason Scott Eastwood was working out in Santa Monica without a shirt or shoes, but WITH jeans and a giant belt buckle -- and you're looking at it.

When you've been blessed with looks and a body like that ... you show it off as much as possible.

Then again ... maybe Clint's son is just prepping for a sequel to his "Funny or Die" video where he plays with dogs. The rest of us just don't stand a chance.

Bobby Brown looked understandably drained as he left the Atlanta hospital where Bobbi Kristina remains in a coma -- and we've learned he's been busy planning a vigil for her birthday.

Bobbi Kristina turns 22 today ... and sources tell us her father has invited several of his family members to join him at the hospital.

That's unusual because while Houston family members have been at the hospital every day -- Bobby and his wife were the only family members from his side allowed at Bobbi Kristina's bedside.

We're told exceptions are being made because Bobby wants everyone to come together for the birthday.

Peyton Manning has not officially decided if he's coming back to play in the NFL next season, but one thing is for sure ... the Denver Broncos QB needs to retire that t-shirt!

The future Hall of Famer and his family were spotted poolside in Miami Beach this week, where the QB committed the personal foul of wearing a shirt in the pool ... a move usually reserved for offensive linemen.

With the news that her boyfriend Chris Brown fathered a now 9-month-old baby girl, Karrueche Tran decided to blow off a little steam Tuesday afternoon by taking her dog Athena for a walk in L.A.

Karrueche got the pup as a Christmas gift from Chris and we're guessing if she had her way ... he'd be fixed too.

Drake did a little importing for his Australian tour -- flying in a hot chick -- from NY to keep him company.

The "If You're Reading This It's Too Late" rapper was chilling at his hotel pool in Perth, Australia, wearing a smoking babe in a bikini, named Bernice Burgos. We're told they met back in NYC, and they've been "knowing" each other since 2012. Drizzy immortalized her in his verse for the song, "Odio."

She's clearly hot enough to warrant a plane ticket half way around the world.

By the way, rare shots of Drake shirtless. He ain't hardcore, but he's looking ... fit.

Rihanna and Leo DiCaprio should be a perfect match -- neither's into settling down with one person for too long -- but now that they're banging ... one of them is way more committed than the other.

We got pics of RiRi and Leo getting cozy recently at her birthday party -- which he helped organize -- and sources at the bash tell us one thing was clear ... Rihanna's the clingy one.

We're told Leo is affectionate enough -- they engaged in plenty of PDA -- but he could barely get a moment to himself. As one source put it, "she's the baddest bitch in the party, but she's following him everywhere."

We're told they've been hooking up for about 3 months, but it's still not exclusive -- more like they're each other's first choice. Not that anyone's crying for either of them.

Nicole Murphy likes 'em big ... real big ... and younger from the looks of things down on Miami Beach.

The reality star was hanging with enormously buff Brit model David McIntosh over the weekend. Considering she split with ex-NFL stud Michael Strahan last August ... it definitely looks like the lady has a type.

But sources connected to Nicole tell us despite their perfect physiques (she's freakin' 47) being so close ... they only hooked up for a photo shoot. No banging. Not yet.

The two of them together though -- quite a body of work.

Kris Jenner welcomed her granddaughter into the family biz ... of shameless promotion -- and North West's game is strong.

Kris was walking through Heathrow Airport in London with Kim and Kanye West's toddler over the weekend ... and had her decked out in a Yeezus tour jacket. Not to be outdone ... Grandma Jenner was wearing a pair of the new Yeezus shoes.

Bonus points to 21-month-old North for that classic Kanye-esque sneer.
