Debra Messing has split from Will Chase.

A representative for the 46-year-old actress told Us Weekly magazine: "Debra Messing and Will Chase have ended their two-and-a-half year relationship but remain close friends."

Though the pair didn't speak much about their relationship, Debra - who split from husband Daniel Zelman, the father of her 10-year-old son Roman - previously revealed she had a lot of "fun" working on 'Smash' with Will, 44, and their other co-star Katharine McPhee.

She said soon after she and Will started dating: "The amount of fun I'm having on this show is so ridiculous -- off the charts already.

"The cast is so accomplished, so committed."

And their romance didn't come as a surprise to the cast and crew of the Broadway drama.

Director Michael Mayer said: "On Broadway, we call it a 'showmance'. That's where people meet and fall in love.

"I don't know where Debra and Will would have met [otherwise]. So 'Smash' brought them together. And the context of their onscreen relationship, I'm sure that triggered a lot."

Since 'Smash' was cancelled in spring 2013, Debra has gone on to work on 'The Mysteries of Laura', which debuted last month, while Will - who has teenage daughters, Daisy and Gracie, from his first marriage - has a recurring role on 'Nashville'.
