You can't teach an old dog new tricks, so the saying goes.
Oh but you can, you can, when a woman a little (or a lot) younger than the old dog takes the leash. See Spot run. See Spot jump. See Spot do a double backflip-cartwheel combo.
That's basically what's happened with Robin Williams and a couple more male stars rapidly approaching (or already at) senior citizen status. Click through to check out the new partners of Hollywood's old dogs.
|Robin Williams and Susan Schneider|
Will the third time be a charm for this funnyman? The comedian and Oscar-winning actor wed graphic designer Susan Schneider in the Napa Valley town of St. Helena, Calif. on Sunday. Her exact age isn't known but suffice is to say that next to the heavily bearded Williams, 60, Schneider looks like a spring chicken. According to the San Francisco Chronicle, the couple have known each other for four years "and been seeing each other for slightly less than that." Reported guests at the wedding include Steven Spielberg, George Lucas and Billy Crystal.
It's the first serious relationship for Williams in many years. He split with his second wife, Marsha Garces in 2008. His first marriage to Valerie Velardi ended in 1988 after a cocktail waitress claimed that she had an affair with Williams and he gave her herpes.
|Paul McCartney and Nancy Shevell|
The erstwhile Beatle found his latest ladybug years ago, but it wasn't until earlier this month that McCartney, 69, and Shevell, 51, tied the knot. The couple first met 20 years ago in the Hamptons, on New York's Long Island, where they both had homes. Shevell has much in common with McCartney's first wife: She's also an American and she's weathered breast cancer. Linda McCartney died of breast cancer in 1998.
But it was the crumbling of McCartney's second marriage (to Heather Mills) and the end of Shevell's first that brought them together. According to the U.K.'s Daily Mail, their romance began with a couple low-key meetings during the summer of 2007, a few months after his separation from Mills and her separation from her husband, Bruce Blakeman.
|George Clooney and Stacy Keibler|
No wonder Clooney always seems so full of life: He's perpetually attached to a pretty young thing. The Oscar-winner's latest girlfriend is a force to be reckoned with -- a former pro-wrestler, Keibler, 32, boasts an enviably buff body. She's also a knockout on the red carpet. Clooney, 50, has had her on his arm at multiple recent events including Monday's Hollywood Film Awards gala in New York. Keibler seems smitten too. On Tuesday she tweeted, "It's the perfect time of year to get cozy with your honey...let these help you set the scene!" along with a link to massage oils and candles she's selling on OpenSky.com.
