Canadian actor Nathan Fillion, who plays Rick Castle in ABC's "Castle," is reportedly dating “Baywatch” actress Krista Allen, the former lover of George Clooney. Reports claimed that the two are happy to be together.

A source told Us Weekly that Fillion met Allen through friends a few months ago. He has been spending time with the actress’ 18-year-old son as well. Both Allen and Fillion are 44 years old.

On her Instagram account, the “Days of Our Lives” actress Allen has posted several photos featuring herself and Fillion -- including a photo taken during Halloween. In the Instagram photo, Allen is seen dressed as a forest nymph, while Fillion poses as a satyr.

“Anyone else feeling horny? #Satyr #ForestNymph #halloweeneve @natefillion,” she captioned the photo.

In October, friend of the couple actress Dina Meyer uploaded a selfie taken with the pair on Instagram. She captioned the photo, “@NathanFillion and I make a delicious @KristaAllenXO #selfiesandwich …. Just for you. Want a bite?”

Allen has been married twice before. After two divorces, she hopes to find happiness with Fillion. Another source revealed to Us Weekly that the actress is “super happy” with her present relationship and has found a “genuinely nice” man to love.

“They are having a great time together,” the source said.

In 1999, Allen divorced production manager and producer Justin Moritt. She and Moritt share legal custody of their son, Jake. In 2010, Allen married Iranian-English rapper Mams Taylor, and she filed for divorce in 2012.

The actress was reportedly dating Clooney in 2002 after they met on the set of “Confessions of a Dangerous Mind." She and Clooney broke up in 2004 when the actress realised that he was not a long-time boyfriend material.

The actress is now starring in the comedy show “Significant Mother” where she portrays the role of a hot mom named Lydia Marlowe, who is dating her son’s best friend. She is also set to star in two upcoming films -- “Eleven Eleven” and “The 420 movie: Mary & Jane.”
