Bethenny Frankel left “The Real Housewives of New York City” four years ago. First she had her own reality show, “Bethenny Ever After,” followed by her talk show, “Bethenny.” Despite being produced by Ellen DeGeneres, it was canceled in February. So what now? Bethenny is reportedly going back to what she knows best — reality TV. Sources say she’ll be back for season seven of RHONYC. It’s reportedly a last-ditch effort to boost ratings for the show and save it from cancellation. Meantime, Bravo has announced that Porsha Williams is being bumped down from main cast member to featured friend status on “Real Housewives of Atlanta.”

We may have all laughed at Gwyneth Paltrow for that “conscious uncoupling” mumbo jumbo, but it seems to be working really well! Chris Martin and his new girlfriend Jennifer Lawrence spent a romantic night in Vegas on Friday. Then Chris jumped on a plane and flew back to LA to host his ex-wife’s 42nd birthday party! Guests included Jennifer Aniston, Nicole Richie, Kate Hudson and her whatever Matt Bellamy. (Are they married yet?) Even though Gwyneth reportedly gave Chris’ new relationship with Jennifer her blessing, she was NOT among the guests.

Justin Bieber and Selena Gomez are definitely back on. They’re both in Paris for Fashion Week. But remember when Selena unfriended everybody on social media and distanced herself from the “toxic” Jenner sisters? Then why did Justin pick up Kendall Jenner from her hotel in a Rolls Royce and take her to a private dinner with no Selena in sight? And what was Selena doing being photographed with Miranda Kerr? Doesn’t Orlando Bloom blame her flirtation (and maybe more) with Justin for the breakup of his marriage??

Wiz Khalifa is accusing Amber Rose of cheating on him during their marriage, but Amber’s friend says that is absolutely untrue. He told a NY DJ that Amber filed for divorce after she caught him in bed with TWINS!! But Wiz is claiming he already told Amber he didn’t want to be married any more weeks before she caught him, so in his mind, they were separated.

TMZ Sports has learned that Michael Phelps had just finished gambling for 8 hours at a Baltimore casino before he was busted for drunk driving. Sources say Michael had been drinking beer while he was gambling in a private VIP room. Michael has apologized for his actions all over Twitter, saying, “I understand the severity of my actions and take full responsibility…I know these words might not mean that much right now but I am deeply sorry to everyone I have let down.”
