It looks like country music superstar Jason Aldean might have some 'splainin' to do. The masters of paparazzi, TMZ, caught the 'My Kinda Party' singer having a little party of his own with a woman who was not his wife earlier this week -- and it was with a former 'American Idol' contestant.

According to TMZ, Aldean was photographed with Brittany Kerr, a dancer with the NBA's Charlotte Bobcats who tried out for American Idol in Season 11. In the photos, Aldean is seen flirting, holding and even kissing Kerr as she sits on a ledge outside 'The Den,' a bar on the Sunset Strip in L.A.

TMZ says Aldean left in a cab without Kerr after the encounter.

Aldean celebrated his 10th anniversary with his wife, Jessica, in 2011.

Aldean approached the subject on his Facebook page, quickly admitting to the indiscretion (after it was plastered all over the Internet, of course) and apologizing.

Here's what he said:
