Tuesday gossip roundup: President Obama gives Jay-Z parenting advice

It looks like the folks behind the attempted intervention for Lindsay Lohan last week had good reason to be concerned about the troubled actress. Several friends of Lohan insist to Radar Online that she’s partying again and out of control, and her dad, Michael Lohan, is reportedly eager to put her under a conservatorship similar to the one Britney Spears’ father used. “People who party with Lindsay have confirmed her excessive partying and getting wasted,” a source says. “Even some of the people who have enabled her partying have come clean and revealed what’s going on.”

Katy Perry’s birthday isn’t until Thursday, she apparently couldn’t wait to get the party started, throwing a lavish Halloween-themed costume birthday party at Los Angeles’ Magic Castle on Friday, according to Us Weekly. And while guests including Kristen Stewart, Neil Patrick Harris and Skrillex were in attendance, the birthday girl — dressed up as a vampire — only had eyes for John Mayer, whose elaborate zombie-hunter costume even involved a prosthetic nose and chin. “They were in their own world. She didn’t even talk to her friends much,” a source says. “It was just her and John. She’s obsessed with him. She said hello to people but then went right back to him.”

While Taylor Swift is over the moon with current boyfriend Conor Kennedy, she reportedly suffered heartbreak at the hands of One Direction member Harry Styles just before meeting Kennedy, according to Radar Online. Apparently the pair dated briefly earlier this year but ended it abruptly when Styles was photographed locking lips with model Emma Ostilly. “Taylor really liked Harry, and even though they weren’t exclusive, he hinted at making it official with her,” a source says. And while Swift was allegedly warned by her personal psychic of impending heartbreak, she was still caught off guard the morning she awoke to a barrage of text messages from Style “begging for a chance to explain and telling her not to believe everything she reads,” the source says. “She immediately googled Harry and found all the stories and pictures of him kissing Emma. She was heartbroken.”

New dad Jay-Z is getting some ace parenting advice from a very distinguished source: President Barack Obama. When the rapper and wife Beyonce met with the president and first lady last month, apparently Obama wanted to know how things were going with 10-month-old daughter Blue Ivy, the president says in an interview with Cleveland’s Z107.9. “I made sure that Jay-Z was helping Beyonce out [with Blue Ivy],” Obama says. “And not leaving it all with mom and the mother-in-law.” The Obamas apparently have a great rapport with Jay-Z and Beyonce. “I’ve gotten to know these guys over the first several years,” Obama says. “They’re good people. They’re down to earth. Beyonce could not be sweeter to Michelle and the girls. So they’re good friends. They really are down-to-earth folks. We talk about the same things I talk about with all my friends.”

“Blue Bloods” star Jennifer Esposito is irate over producers of the hit CBS show sidelining her character due to the actress’ health issues, and she’s taken to Twitter to vent. “CBS put me on unpaid leave and has blocked me from working anywhere else after my doctor said you needed a reduced schedule due to Celiac [disease],” Epostito writes. “CBS didn’t listen to my doc and I collapsed on set. Which everyone saw! After a week off, my doc said I could return to work but CBS implied that I was not truly ill and this was a scheme to get a raise! It’s been almost two months without bringing me back to work and keeping me from working anywhere else! Absolutely shameful behavior.” The show’s studio has responded with a statement saying that Esposito “is a wonderfully talented actress and we hope that she will be able to return at some point in the future.”
