Ryan Lochte is officially back home ... and he's ditched that ridiculous hair. 

Lochte arrived to his Charlotte, NC crib with girlfriend Kayla Rae Reid Saturday afternoon ... and one thing's for sure, he's not looking too jovial. 

As TMZ reported ... the USOC says it's still looking over Lochte's case and will make a decision regarding any possible discipline in the coming weeks. 

Ryan Lochte really stepped in it, and Johnny and Amber have settled their legal score. So we gotta ask ... 

Justin Bieber has made it clearer than ever -- Selena ain't his type no more -- because he hit the town in London Friday night with a Sofia Richie lookalike. 

The Biebs and the chick hit up Tape nightclub. Here's what we don't know -- who she is, and what he's done with Sofia. He and Sofia boarded a private jet a few days ago but she was MIA Friday night. 

TMZ's becoming your only option to see JB, now that he's 86'd himself from Instagram.

Miley Cyrus and Liam Hemsworth showed lotsa love during a sushi run Friday in the Bu.

They hit up Bui Sushi and for anyone who doesn't know ... their fashion choices are dead on Malibu.

Don't know when they're getting hitched, but clearly they're doing good.

Rihanna was in a precarious position Friday night in London.

She knew how to do denim for sure, as she left Tape nightclub ... the same place Justin Bieber was partying with a mystery blonde.

28 Justin ... it's the new 17.

Jonathan Tucker has seen what many wish they could've ... Nick Jonas naked. 

Tucker is set to appear on this week's episode of "Allegedly" with Matt Weiss and Theo Vonn ... and he gives the scoop on Jonas' goods. 

You'll have to take a listen to just how articulate Jonathan gets when describing Nick in his bday suit ... it's pretty funny. 

You can listen to the full podcast here when it drops on Tuesday.

Kanye West leaves no stone unturned when it comes to finding talent ... even if that talent is standing in line at one of  his Pablo stores. 

Yeezy's opened up 21 shops across the globe sporting his Pablo collection this weekend ... and Cesar Martinez was one of the first in line at the L.A. stop. Lucky for him, Scooter Braun stopped by the shop just as he was on the phone with Kanye, who asked to speak with someone in line ... Cesar was the lucky fan.

Martinez tells us he's a designer and let 'Ye know it, asking for a chance to show him some of his work. Lucky for Cesar, Kanye obliged ... and we're told he's setting up a time to take a look at his designs.

Not only that -- Martinez also scored some tickets to Kanye's upcoming tour -- not a bad day.

Columbus Short has some BIG things about to happen in his life ... he's gonna be a husband AND a new dad.

Short tells TMZ in just 5 months, he and new fiance Aida Abramyan are expecting a boy. Columbus says he and Aida have been on and off for years but he just recently popped the question. We're told the two plan on getting married some time before January before the baby is born.

As for a name for their kid ... Short says they've got one picked out ... but they're gonna keep it under wraps. 

Congrats!!

Mel Gibson just agreed to pay baby mama Oksana Grigorieva 50% more than she was getting last month, but the trade-off is that she has to skedaddle from his home.

We've learned Mel and Oksana have been squabbling over child support for 6-year-old Lucia. Oksana was pulling in $20k a month but wanted a small increase -- to $100k a month!

We're told they went back and forth and struck a deal. Mel is now paying Oksana a skosh under $30k a month. But in return Oksana agreed to vacate Mel's $2.4 million rental home in Sherman Oaks. We're told she's rented a pad in Malibu.

It's pretty amazing. TMZ broke the story, Mel was willing to pay Oksana $15 MILLION to settle their child support and alleged domestic violence cases -- provided she keeps those incendiary, racist tapes secret. After signing the agreement, Oksana disavowed it and went for more.

She ended up with a $250,00 settlement.

And file this under glass half full ... Oksana had 50 lawyers in her epic battle with Mel, so her latest -- Brian Kramer -- settled and got her a 50% increase, which is better than the scores of lawyers did before him.
