The crowd in Columbus, OH got a very special surprise on Saturday, August 20, when Britney Spears brought out a special guest to make a cameo appearance during the last song of her concert! Nope, it wasn’t former headliner Nicki Minaj — it was her oldest son, Sean Preston!

The 5-year-old, who’s Brit’s son with ex-husband Kevin Federline, was smiling the whole time as he held mommy’s hand and waved to the audience. Britney’s such a cool mom!

Watch the video below!

Joe Jonas‘s solo career is really taking off! The 21-year-old pop star is going on tour with Britney Spears on her Femme Fatale Tour in Europe. Not only is Britney, 29, one of the world’s biggest stars, she was also one of Joe’s first crushes!

“She was the first girl I ever had a poster on my wall of, and her album was the first CD I ever bought,” Jonas told People. “It’s so funny to think I had that on my wall and here I am about to perform with her.”

Joe is looking forward to performing music from his first solo album, Fastlife, which is set drop Oct. 11.

“I’ll be playing more music than I have the past few times I’ve performed live so far,” he said. “It’s going to be really fun to perform some of my music from the album.”

Joe and Britney will first perform together in the States Aug. 5 and then he’ll join her again for her nine European concerts starting Oct. 16. We’re so proud of him!

She wore a series of skimpy outfits during the show, which largely received rave reviews, which accentuated her curves—and in some cases it seems the outfits may have been a tad too snug!

Skimpy outfits aside, Britney dazzled the crowd with hits such as “I’m A Slave 4 U” and “Toxic,” as well as new tracks, such as “Big Fat Bass” and “I Wanna Go”.

According to Rolling Stone, the show was “her flashiest, fastest moving, and most entertaining production yet.” And while Nicki Minaj was the opening act, the magazine wrote “the night belonged to Britney: She managed to prove that she’s still progressing as a showgirl. Not only that, she’s doing it better than even die-hard defenders would’ve predicted.”

But back to Britney’s bod: What do you think? Vote Below!

Britney proves yet again she still has it as critics praise her performance on opening night of her ‘Femme Fatale’ tour!

Britney Spears has had her share of highs and lows, but one thing she always manages to deliver on is amazing tour performances, and her latest “Femme Fatale” is being dubbed her best yet! Britney kicked off her latest tour June 16 in Sacramento, and according to critics she was at the top of her game! What great news for Britney and her fans!

The Sacramento Bee wrote, “Though Spears performed like a pro throughout the show, hitting all her marks, she had shown hesitancy in her movements – natural for the first stop on a tour. But that hesitancy vanished when she put on the denim. She seemed at ease.”

RollingStone.com went a step further saying, “the night belonged to Britney: She managed to prove that she’s still progressing as a showgirl. Not only that, she’s doing it better than even diehard defenders would’ve predicted. At 29, the pop star whose career seemed in danger of ending just a couple years ago has shown that she’s back – hopefully this time to stay.”
