Though Kelsey Grammer and wife Camille Donatacci split before this year's Tony Awards, he asked her to fly to New York to attend the ceremony and put on a happy marriage face, sources tell the New York Post.

The 'Frasier' star, 55, broke it off with his wife of 13 years last month. "Kelsey was so cold. He told her it was over and he wanted to see other people, but still asked her to be at the Tonys," the Post's source says.

Donatacci, 41, stayed at the London Hotel and held up at public appearances with Grammer, but the actor wouldn't allow her into his apartment or discuss any sort of reconciliation, the paper reports.

Grammer moved to New York earlier this year to star in 'La Cage Aux Folles' on Broadway, but "became more distanced from Camille," the source reports. "He was living the single life."
