"So much fun on set with Ricky!" Lea Tweeted yesterday, along with a photo of her and the single dad of three-year-old twin boys, Valentino and Matteo. "He's seriously the sweetest and such a good fit for our show!" 

Lea also shared that she has known Ricky since she was a young girl. Believe it or not, the pair met while they were both in Les Miserables on Broadway in 1996!
