After staying by his new lady's side all night, Groban tweeted his support for the event's cause. "Lovely night all around," he wrote. "Always happy to support Barbara Davis and her #CarouselOfHope ball to raise money for Diabetes research."
Speaking to Details last year about his split from January Jones, Groban admitted that he and the "Mad Men" actress were "madly in love," telling the magazine he's "a real romantic at heart." (He declined to confirm or deny rumors that he'd hooked up with Katy Perry.)
In 2012, Dennings reportedly dated her "2 Broke Girls" co-star Nick Zano,.
