Ryan Seacrest's New Love!

Seacrest, 34, met Waltz during a night out at Guy's, a West Hollywood lounge. Waltz, who has previously worked at other L.A. hotspots including Les Deux and Italian restaurant Bella, is an aspiring actress, a source tells PEOPLE.
"They've been together for a few months now," says the source.
After wrapping his American Idol duties last week, Seacrest whisked Waltz off to Paris for a weekend where the couple displayed a lot of PDA.
The brief respite served as a prelude to a busy spring: Seacrest's radio show, which garners a weekly international audience of 20 million across 130 stations, will expand to a fourth hour of programming on May 4.
In December, Seacrest's mother Connie told momlogic.com she wished her son, the producer of the NBC reality show Momma's Boys, would have more time to date. "That would be wonderful for him," she said, "and we'd stand a better chance for him to have a relationship."
Seacrest has been linked previously to singer Sophie Monk, Amazing Race star Shana Wall, and actress Teri Hatcher.
