Kate Gosselin Takes Her Twins Jonas-Watching

Mother of eight takes 8-year-old daughters to a Jonas Brothers concert in Philadelphia

Jon Gosselin may be the one being mauled by the "Lovebug," but it's Kate Gosselin's socks that got rocked off tonight.

Kate, officially queen of the world in her 8-year-old daughters' eyes, took twins Cara and Maddy to Thursday's Jonas Brothers show at Wachovia Center in Philadelphia. 

An eyewitness tells E! News the trio and one of the twins' friends rode in a black stretch limo to the concert, which started shortly after 7 p.m.

"They were really happy and excited," the source said of the three little ones, all smiles as they arrived at the arena.

And we presume Kate was pretty happy, too—not only because of the looks on her kids' faces, but because a newly single lady should have the chance to put her hands up, up in the club, because she just broke up and is doing her own little thing.
