From Showtime:

On the rebound from Stephanie, Chris breaks an unwritten band rule and starts dating a young singer/songwriter named Olivia. All though he finds her efforts at songwriting painful, she's very sexy, and her father owns forty acres of the best surfing beach in California. But their new relationship takes a direct hit while attending a ceremony at the San Francisco Zoo, where Chris' record company has adopted an animal in his name. To his embarrassment, ‘Isaak,' an ornery old chimp with no toilet training and great aim, doesn't seem to think much of Chris' taste in women.

Yola suffers a different kind of humiliation when she discovers her mom's new love interest, Brad, is a guy she previously dated, and dumped. Mom's convinced she has finally found true love, but Yola suggests that Brad is actually trying to get even, and she's determined to beat him at his own game.

Meanwhile, Anson's manliness is put to the test when he starts dating the Zoo's herpetologist. But her

Chris must do some damage control when his girlfriend, Olivia, arranges for Richie Sambora to perform with him, without checking with Yola first.
