Justin Bieber threatened with handcuffs at Mayweather fight

Relationship roundup… Kardashian and Jenner sisters panel… Has Zac Efron relapsed?… Arnold Schwarzenegger hosts “Celebrity Apprentice”… and Justin Bieber threatened with handcuffs at Mayweather fight

CELEBRITY RELATIONSHIP ROUNDUP: Tiger’s ex Lindsey Vonn is reported dating Britney’s ex Charlie EbersolRebel Wilson and her comedian boyfriend, Mickey Gooch Jr., are done. It was a friendly break, and a source told “Us Weekly” that they may end up back together. And after a little over a year, Christian Milian and Lil Wayne are done. It actually ended about a month ago. Sources say it was a friendly, mutual decision. Blame it on their busy schedules.

The Kardashian and Jenner sisters gathered at the Soho Apple Store in NYC yesterday for a panel discussion. You scoff, but these sisters know how to work social media to their very lucrative advantage. The sisters were announcing the launch of their individual apps. And, according to Kim Kardashian, they’re hoping to come up with some kind of comment control that would “make it a very happy, uplifting place, not a negative place.” She added, “I don’t think that’s really good for anybody’s soul.” Khloe said, “We want to hear from our fans, but there’s got to be a way to do that where things are still filtered because we want to start changing the way of social media. It’s about mind, body and soul.” Kim’s app costs $2.99 a month and it gives you access to her website, which includes video blogs with makeup and selfie tips. For that same price Khloe’s app gives you unlimited access to her workout videos and she also used one video blog to teach us how to stack cookies in a cookie jar. It sounds silly, but I was highly entertained…….

Zac Efron’s friends are concerned that he’s relapsed. Two years ago, Zac quietly went through rehab for substance abuse issues and things seemed to be going great for him……until recently. A source told RadarOnline.com that at a recent cast party in Atlanta, Zac seemed to be “totally out of it” and kept complaining to everybody how hard is was to stay sober while filming “Neighbors 2” because it’s a “drug-fueled movie.” The source says Zac’s girlfriend Sami Miro was stunned by his behavior because they started dating about a year after he got sober and she’s never seen him like this.

It was announced yesterday that Arnold Schwarzenegger will take over for Donald Trump as host of “Celebrity Apprentice” this coming season. Donald tweeted his congrats to Arnold yesterday, saying, “He’ll be great & will raise lots of $ for charity.” And, “To all my fans, sorry I couldn’t do The Apprentice any longer — but equal time (presidential run) prohibits me from doing so.  Love!”

Justin Bieber was there to watch his BFF Floyd Mayweather Jr. beat whoever and wanted to get up in the ring to celebrate. But one security guard was having none of that, refusing to let Justin go into the ring. One account says Justin pulled out his “Do You Know Who I Am?” card but another says he didn’t. Either way, the guard wasn’t letting Justin up there, asking him, “You wanna be escorted out in handcuffs, young man?” Well, that’s a redundant question, don’t you think?
