TMZ has obtained the 911 call placed January 12 by Heather Locklear's sister ... the tape is heavily redacted because of patient confidentiality, but TMZ has learned the nature of the emergency.

Law enforcement sources tell TMZ ... Heather's sister told the dispatcher Heather was having intense stomach pains and was in severe distress. When paramedics arrived they performed some tests and quickly decided her condition was so serious Heather needed to be transported to a hospital and placed in ICU immediately.

TMZ broke the story ... paramedics examined Heather after her sister made the emergency call, and determined Heather needed to be hospitalized after she had taken a dangerous combination of prescription drugs and alcohol.

It's her second drug-related emergency in the last couple years -- Heather was hospitalized back in 2008 for what the 911 operator described as a "suicide attempt" ... after her doctor became concerned Heather may have OD'd on prescription pills. It turned out to be a false alarm.

Christine Lakin is best known for playing youngest daughter Al on the blended family '90s TV series "Step by Step." Guess what she looks like now!

Dwyane Wade got a SICK $230,000 sports car at his 30th birthday party in Miami this weekend -- but the most impressive part of the gift is how it was AIRLIFTED into the hotel pool without a scratch.

The car is a brand new 2012 McLaren MP4-12C -- given to him for FREE by the owner of a local luxury car dealership. Wade is the brand ambassador for that particular dealership.

The guy wanted the presentation of the car to be super-fancy -- with the McLaren waiting for Wade on a platform in the middle of the hotel pool. Problem is, you can't just drive that thing inside the hotel.

Instead, the car was loaded up onto a crane in the alley next to the pool area ... hoisted above the hotel wall ... and carefully lowered onto the waiting platform, positioned inside the pool.

Props to the crew -- because the whole thing went off without a hitch ... and D-Wade accepted his present in front of famous friends like Usher, Common, T.I., LeBron, and Chris Bosh.

D-Dub even got a shout from Vogue chief Anna Wintour ... who said, "I hope we'll see you back at NY Fashion Week in September, because you're my favorite person to sit next to at the shows."

The rich get richer.

Betty White turns 90-years-old today -- and we've got a look at the "Golden Girl" from her days at Beverly Hills High School!

Check out her yearbook photo above, plus shots of Jennifer Lopez, Sandra Bullock, John Stamos and more.

A new series of Casey Anthony photos -- posted on Twitter by the same person who posted the previous pics -- surfaced online ... featuring the dog Casey said she adopted in an earlier video.

Casey still has the same short blonde hair and glasses she was sporting in the other photos.

It's still unclear who's releasing the photos. Anthony's attorney, Jose Baez, told Geraldo Rivera he would go after him/her ... but then Baez quit as Casey's attorney just days later.

Just because these guys are over 40 doesn't mean they're over the hill!

Check out which male stars are still flaunting some seriously shredded stomachs -- with a few who look better most 20-somethings out there.

Jennifer Lopez got in a classic post-divorce jab on Marc Anthony -- flaunting her now wedding-ring-free left hand in her ex's face ... as they sat inches apart.

J.Lo and Marc reunited briefly at a Pasadena news conference to promote their upcoming talent search TV show for Univision. The former couple shared a stage and answered a few questions ... but only about the show.

We know it was probably unintentional, but Marc is definitely checking out that hand.
