Nevermind the fact that Britney is killing it in that swimsuit!

The 33-year-old pop star has been spending extra time hanging out with her two little dudes lately! From this video of their pretty impressive Lego work....

To this field trip to a chocolate factory! Britney wrote, "Chocolate! Yay! Me and the boys at the chocolate factory."

It's possible that Britney is taking fashion clues from North West, and her cousin, Penelope Disick. On Wednesday, Kim Kardashian posted a picture of the two cuties with a new friend they made on their epic St. Barts vacation, writing, "Little mermaids."

Meanwhile, Britney Spears is about to go from sunscreen to the small screen, when she guest stars on The CW's Jane the Virgin in the upcoming season! Showrunner Jennie Snyder Urman had the scoop for ET.

"We've got Britney Spears!" Urman gushed. "We're just so excited, and I'm still freaking out."

The executive producer dished that Spears will be playing an "exaggerated version" of herself in episode five of season two. "It's in the same sprit of when Paulina Rubio came on [to the show in season one]," she said. "It was still Paulina Rubio, but it was a fictionalized Jane the Virgin version."

OK... now we can take a second to mind how Britney is killing it in that swimsuit!

The "Oops, I Did It Again" singer is in amazing shape of late, and flaunted a jaw-dropping dress at the Teen Choice Awards, where she accepted the Candie's Style Icon award.

"Fashion has always been something I've loved to experiment with," Spears said from the podium. "It gives us all a chance to express ourselves and our own personalities and to shine in our own way. To all the teens out there watching, be fearless in your choices and don't be afraid to be yourself."
