Celebrating together again

Just when it looked like Whitney Houston was finally done with Roxbury-bred R&B singer Bobby Brown, the toxic twosome have apparently gotten back together. The hard-partying pair, who divorced in April after 14 tumultuous years together, were photographed this week at Joe's Crab Shack in Alpharetta, Ga., and the pic was posted yesterday at TMZ.com. The couple may have been celebrating Whitney's 44th birthday, which was yesterday.

Alicia Silverstone looked like she might cry. Speaking at Babson College yesterday, the enviro-friendly actress recalled a trip she took to the Amazon with Woody Harrelson. "They're clear-cutting these precious places so that we can have our cheap burgers," said the star. "The planet is suffering so greatly." Silverstone, who first caught our eye in the Aerosmith video "Cryin' " and then hit it big in the film "Clueless," was invited by the Kushi Institute to talk about her "green" lifestyle. She spoke of solar panels, organic underwear, a clothesline -- "I feel like I'm in Tunisia or Italy . . . I don't know why hanging clothes is so fun, but it is" -- and a questionable habit of not flushing. "At my wedding, I wanted to put up signs that said, 'You don't have to flush,' " she said. (Perhaps persuaded by her rocker husband, Christopher Jarecki, Silverstone decided to plunge that idea.) A vegan for nearly a decade, the actress said children wouldn't eat meat if they knew where it came from. "Maybe just one little Satan child would," she said. Standing on stage yesterday in bare feet, Silverstone, 30, said she's just doing her part. "Doing a little is better than doing nothing," she said.

Justin Timberlake is bringing SonsieBack. The singer, who plays the TD Banknorth Garden tonight, dined at Patrick Lyons's Newbury Street restaurant the other night. (We're told JT's been running around town with Tom Brady's right-hand man Will McDonough.) Coincidentally, Revs stud Taylor Twellman was eating at the next table with a few teammates, and former J. Geils singer Peter Wolf was also lurking about.

As they prepare to start shooting here, the producers of "Bachelor No. 2" -- starring Dane Cook, Kate Hudson, Alec Baldwin, and Jason Biggs -- are looking for extras. Specifically they need well-dressed men and women for a wedding scene, and "experienced exotic dancers/strippers." Interested?

House Speaker Sal DiMasi and Senate President Therese Murray made beautiful music last night. The Democratic leaders set aside their political differences to guest-conduct the Boston Pops, taking over for Keith Lockhart. The occasion? It was the last night of the National Conference of State Legislators. The night before, we're told, Murray hosted a dinner at Joe Tecce's, and former DNC chairman Terry McAuliffe was there pressing the flesh on behalf of presidential wannabe Hillary Clinton.

Her 'Hour' to shine

In a little white dress, Kate Bosworth looked radiant as ever at the LA premiere of "The 11th Hour." The Cohasset cutie was joined on the red carpet by "Entourage" actor Adrian Grenier, actress Q'Orianka Kilcher, the documentary's directors Nadia Conners and Leila Conners, and producer Leonardo DiCaprio.

Girl talk

"Grey's Anatomy" star Ellen Pompeo blames the media for all the attention being paid to Hollywood socialites such as Paris Hilton. "We're so focused on the wrong things," the 37-year-old Everett native told Los Angeles Confidential magazine. "We're teaching young girls that this is what they should be focusing on: rich and famous girls who are rich and famous for nothing." Pompeo also calls the media "irresponsible" for the speculation about her eating habits. "I just worry about the girls who look up to me I don't want them to think I starve myself or don't eat, and that to be like me that's what they have to do."
