SPOILER ALERT: Sean Lowe can cut back on the spray tanning now that his time on the dance floor has come to an end. He and his professional partner Peta Murgatroyd were eliminated from “Dancing with the Stars” last night. In his parting words, Sean said he enjoyed every second of this experience, reminding us all, “I’m just a normal guy from Dallas.” Er, you WERE A normal guy from Dallas. Hollywood has RUINED you, Sean! RUINED you!!! But it was great seeing Jason Derulo perform his new single, “The Other Side,” last night. He started off by balancing on his head, which is a HUGE deal because he broke his neck during dance rehearsals last year and doctors were afraid he’d never walk again. And in a BONUS SPOILER ALERT: Extreme skier Rory Bushfield beat out former “Baywatch” star Nicole Eggert to win the first ever “Splash” celebrity diving competition.

I guess that $3 million dollar mansion he gave her didn’t take away her pain. Julianne Hough ran into Ryan Seacrest at the Soho House in LA Saturday night. Ryan was having dinner with a TV executive when Julianne walked in. Rather than pull that whole immature “I’ll pretend like I don’t see you and you pretend like you don’t see me” routine — a la John Mayer and Jennifer Aniston — Julianne walked over and gave Ryan a kiss. He excused himself and the two of them went into a quiet area to talk. Sources say they had a pretty emotional conversation, and it looked like Julianne was wiping away tears. Ryan then walked her back to the table, they said their goodbyes, and the dude just walked away

Kim Kardashian was banned from the Met Gala last year, but because of her relationship with Kanye West, who was one of this year’s performers. Anna Wintour allowed Kim to tag along as Kanye’s “plus one ” — “plus two,” if you want to be technical about it. But now Kanye might find himself banned from next year’s Gala after his performance. After Blondie left the stage, Kanye jumped on the stage and just started screaming. And rather that stick to the set list, he started performing all these songs off his new CD — stuff nobody’d ever heard and none of his big hits. And if you were wondering what the new tracks sound like, one source said Kanye was “basically screeching into the microphone” the entire time.

Chris Brown boarded a private jet in Burbank to fly to NY for the Met Gala, but as soon as the plane took off, the cockpit filled with smoke and the jet had to turn around for an emergency landed. Chris just caught another jet and made it to the ball in plenty of time. But no, that wasn’t Karrueche Tran or Rihanna on his arm. It was some mystery brunette we still haven’t identified. About 3:30 am, Chris and his 20-person strong entourage headed to the Griffin club in the Meatpacking District, where Chris danced shirtless on the table and ordered several $15K bottles of Ace of Spades champagne. The group partied hard for a solid 40 minutes, but dang it! They turned around and it was closing time.

Rihanna wasn’t at the Met Gala with Chris or anyone else because she was performing a rescheduled concert in Boston that night. She had canceled the March 10 show because of laryngitis, but on Monday night, her opening act — A$AP Rocky — missed the show because now he’s sick. Several fights broke out in the crowd as they grew more and more impatient for Rihanna, who finally took the stage an hour and a half late. The crowd booed her but eventually got over it. One tabloid is reporting she was late because she was watching the Chicago Bulls play the Miami Heat.
