Michelle Williams and Jason Segel enjoyed a ''lovey-dovey'' date last night (19.06.12).

The 'My Week With Marilyn' actress snuggled up with the 'Five Year Engagement' star as the couple dressed up smartly to enjoy a romantic evening watching James Corden's 'One Man, Two Guvnors' Broadway show at the Music Box Theatre on West 45th Street, New York.

An audience member told the New York Post newspaper: ''They look very lovey-dovey. She looks so pretty in white, and he's in a suit.''

The couple have been dating for three months and it's not the first time they have been spotted getting cosy in public. The blonde beauty was seen leaning in and kissing Jason on The Cheek and rubbing his back at the after-party of the premiere of his latest movie 'The Five Year Engagement' in April.

The 32-year-old actor was also spotted holding the 31-year-old star's hand and whispering in her ear at the New York event.

Jason has recently been bonding with Michelle's daughter Matilda - her child from her relationship with late actor Heath Ledger, who died of an accidental drug overdose in January 2008 - and looked to be enjoying his responsibility as he took the six year old out to play with her scooter.

Jason was also recently spotted holding his cell phone, which had photo-booth style images of Michelle taped to the back decorated with hearts and containing the words, ''I love you''.

Michelle and Jason have been friends for years after meeting through the actress' friend and the actor's 'Freaks and Geeks' co-star Busy Philipps.
