So why is he in a "Latino comedy" then? Also today: Kevin Spacey has gone shopping, we now know who will play Lance Loud, a series renewal gives us hope in the world, and Chace Crawford is moving upstate.

A mystery celebrity will be coming out of the closet on the cover of People on May 5 and lots of people are talking about who it's going to be. Well, it's time to toss out names and respective odds.

Today Ricky Martin dropped a crazy truth bomb on the world and acknowledged he is a "homosexual man." Yeah, duh! But he's not the only public figure still hiding—unsuccessfully—in the glass closet.

Gerard Butler and Jennifer Aniston are all up in our grill again. This must have something to do with those gay rumors. Every famous male gets them at some point, but how can you tell whether or not they're true?

We like Zach Galifianakis so much we won't ruin this post by complaining that anyone who first discovered him by watching "The Hangover" doesn't deserve to call themselves a Galifianakis fan. Whoops! Anyway, he is starring in a new film.

• The Lohan family drama goes on. Another recorded phone call has been released and this one features Dina Lohan telling Lindsay's father Michael that their daughter once punched her and kicked her out of the car. Naturally, LiLo quickly responded on Twitter and called her father a whole bunch of names. And now Papa Lohan has countered by promising to release even more tapes in the days to come. So, no, this saga is not even close to over. [P6, People]
• Alec Baldwin says he has "a great ass." Please make a note of it. [Us]
• Paul Johnson-Calderon, the bow tie-wearing social gay set to appear on Tinsley Mortimer's upcoming reality show, is in trouble again. He was caught on tape snatching purses on the LES earlier this year; now he's been caught on camera vandalizing a friend's Union Square apartment building. Calderon's defense? "It's not like rock stars don't vandalize hotel rooms and such all the time." Yes, but you're not a rock star, buddy. [P6]

Page Six today has a not-very-thinly-veiled item about Anderson Cooper going on a very gay vacation with his very gay boyfriend who owns a very gay bar. Enough: Anderson Cooper is very gay. It's time he said it.

Two teenage celebrities might be getting married, and therefore: doing it. Robert Pattinson's life is invaded by aliens. Paula wants back on Idol, and I want back in the womb. Madonna, Sinatra, Spears, Spacey. Presenting your Sunday Morning Gossip Roundup:

It's a big birthday for Jennifer Lopez. She's celebrating the big 4-0 today. Other people who will be blowing out candles this fine Friday: Broadway star Kristin Chenoweth is turning 41.

Until tonight, we'd no idea that David Letterman was so painfully ignorant about Twitter. He thinks it's something people have to pay for! So Kevin Spacey pulled out his Blackberry and attempted to explain it all to him.

Famous actor Kevin Spacey is going to prison! To... interview criminal lobbyist Jack Abramoff. For an upcoming film. A film that sounds just weird.

• It looks like Bethenny Frankel will be staying single a little while longer. A day after she and A-Rod were spotted on a "date" at a steakhouse in Florida, the Yankee was seen "canoodling" with a "trashy blond girl" at the Delano. Oh, well. [NYDN]
• It's official: Heidi Klum is with child. [Us]
• Good news for Jesus Luz: Not only is he back together with Madonna, he's booked Dolce & Gabbana's next campaign, too. [WWD]
• Estée Lauder CEO William Lauder says he's not paying his baby mama Taylor Stein the $500k a year she was promised because she violated their confidentiality agreement. Her lawyer says it was actually William's wife Karen who leaked word of the baby to the press. [NYP]

Kevin Spacey can't go shoe shopping without hanging out in secret back rooms; Madonna can't get rid of her boy toy and Gwyneth Paltrow can't keep secrets.

Movie deals for funny men, a TV deal for a funny woman, AMC branches out, SAG and AFTRA become friends again, and The Simpsons make the mail.

The fight over the impending SAG strike has gotten uglier, now with an anonymous emailer urging the Hollywood community to awards-boycott eight well-known actors who do not support a referendum that would authorize a strike.

As Esquire once famously teased, "Kevin Spacey Has a Secret," and now, finally, that secret has come to light: he's a good samaritan! Already notorious for a well-intentioned, late-night dog walking that turned ugly in the most homoerotic way, the actor was snapped this weekend in Croatia enacting a "pay it forward" so unorthodox that it would make even a newly R-rated Haley Joel Osment blush. Says The Sun:

• It's not that Kevin Spacey wanted to pull down his friend's boxer shorts so much as that Croatian nightclub tradition basically required him to do so. [LA Rag Mag]
