Move over Matt — Katie Couric's (search) new squeeze is a boyish-looking jazz trumpeter named Chris Botti. (search) The musician, 42, who has opened for pop star Sting and is promoting his own CD, told USA Today that he's nuts about the morning show pixie.

"She's brilliant and beautiful and really, really fun," Botti says of Couric, 47. She knows about music, "but then, she's up on everything. She's so intelligent."

Rumors about Botti and Couric have been swirling for weeks. She recently broke up with Red Sox co-owner/media mogul Tom Werner.

Couric first met Botti on the set of the "Today" show (search) a few years ago when he showed up to play backup for an appearance by Sting. They were more properly introduced a few weeks ago at a party in New York and have been dating ever since, he says.

"It's been interesting going out in public with Katie, but this is all very new to me. I'm taking it one day at a time," he says.

Botti has been named one of People magazine's "50 Most Beautiful People," and has worked with Joni Mitchell, Natalie Merchant and other music stars. He joined Paul Simon's band in 1990 and worked with the singer for five years.

His new album, "When I Fall in Love" hit stores at the end of September.
