Kate Gosselin Takes Twins to Jonas Brothers Concert

Jon Gosselin isn't the only one having fun. Kate Gosselin spent Thursday evening with three much-younger men: the Jonas Brothers.

The mother of eight took two of her daughters, 8-year-old twins Cara and Mady, to see Kevin, Joe and Nick Jonas at their concert at the Wachovia Center on Thursday in Philadelphia.

The trio and one of the twins' friends arrived at the show, which started shortly after 7 p.m., in a black stretch limo. No film crews were with them at the concert. Shooting for Jon & Kate Plus 8 -- which returns to TLC on August 3 -- went on earlier in the day at the Gosselin's $1.1 million Wernersville, Pennsylvania, home.

Meanwhile, Jon has been busy with a new girlfriend in NYC. He made headlines on Wednesday after having dinner in the Hamptons with Star tabloid reporter Kate Major -- as well as Michael Lohan and Real Housewives of New York City star Jill Zarin.
