Graduated With Honors: It may have taken them two or twelve attempts, but so far Lindsay Lohan, Britney Spears and Keith Urban appear to be holding steady after their most recent rehab stints. After promptly driving while wearing cokepants two weeks post-Promises last summer, Lindsay's stay at the trendy Le Cirque led her into the loving lesbian arms of Sam Ronson, the nipple-baring cover of NY Magazine, and out of the vapid Living Lohan spotlight. Britney Spears struck out at three different centers early last year only to wind up spending most of her winter strapped to gurneys, but ever since being treated for “bipolar disorder” at UCLA, the comeback queen has gone an entire three months without dropping a single baby or exchanging fishnets with a single bimbo. As for soon-to-be-dad and onesie expert Keith Urban, the former freebaser’s stay in an unknown center months after marrying Nicole Kidman has proven successful so far, though he is approaching his one-year anniversary since Rehab Stay Number 1. But surely the arrival of a bundle of batface joy will keep him on the straight and narrow.

Wild Cards: First-timers Eva Mendes and Kirsten Dunst both tried to mend their respective drug, booze, depression, and “method acting” vices at Le Cirque this year, but only time will tell if Eva’s so-called research will show its Oscar-worthy face on-screen. As for Dunst, AA classes haven’t stopped the onslaught of gossip claiming the shaky star is still wobbling her way around New York and perfecting her drunk faces of yore. And then there’s our favorite alcohol-snorting songstress Amy Winehouse, who’s tried out so many rehab centers we stopped counting long ago. Sometimes sane on the stage, sometimes making out with Pete Doherty, we can’t even look away from her ever-growing beehive long enough to ponder her chances of success.

Newest Students: Last month Steven Tyler checked in to Las Encinas, suggesting even the glamorous druggie rocker crowd hasn’t entirely cleaned up its act despite Mick Jagger’s immortal hips and Keith Richards’ indestructible face, but spending only three weeks in the slammer and blaming the stay on “foot pain” lead us to believe Tyler’s ongoing love affair with rehab centers isn’t quite over yet. Which leads us to Heather and Shawn. As Us reports, Locklear’s mysterious March evening of 911 calls and denials wasn’t as innocent as her rep claimed at the time. Denise Richards’ personal doormat is said to be dealing with “anxiety and depression” at an in-patient facility, while Larry King’s latest trophy of ten years is allegedly headed to rehab for munching on Generation Rx’s candy of choice: painkillers.

• HEATHER LOCKLEAR IN REHAB FOR ANXIETY, DEPRESSION [Us]

Meg Ryan appeared on the special issue's third cover, following Jodie Foster and Cindy Crawford, in 1994. Happily married to Dennis Quaid and still enjoying that whole America's Sweetheart phase, Ryan was a natural choice. But as we all know, five years later Ryan entered an affair with Proof Of Life co-star Russell Crowe, which led to divorce, trout pout and making dirty movies. Oops. As for Mel Gibson, People's 1996 cover star, beauty gradually descended into bigotry and all kinds of sugar tit-laden anti-Semitic madness we just don't even feel like discussing in detail at the moment.

The very next year, none other than Tom Cruise and his uber-serious mug graced the cover. Officially adored by the world after appearing in Jerry Maguire the year before, Cruise was still married to Nicole and every woman in the country felt that Cruise truly "completed" them. But after hiring a divorce lawyer, a beard (in the form of Penelope Cruz), and a new wife, Cruise's beauty is now only recognized by those with OT-V clearance and above. And finally, 2004's issue featured a blissfully married Jennifer Aniston, who sadly spent most of her interview "laugh[ing] off speculation of then-husband Brad Pitt's rumored romance with Mr. & Mrs. Smith costar Angelina Jolie." Again, oops.
