Jon Hamm and Jennifer Westfeldt have shrugged off rumours that they have split.

The Mad Men star had been rumoured to have broken up with his long-term girlfriend before checking into rehab for alcohol abuse, but a rep for the couple shot down the story that their relationship was on the rocks.

A statement said: “The story that appeared in this week’s edition of In Touch magazine is not true. The only gentleman Jennifer visited regularly in Connecticut was Jon, while he was in rehab. They continue to ask for the public’s understanding and sensitivity during this challenging time.”

Jennifer had been said to have split with Jon before he went into rehab at Silver Hill Hospital in New Canaan, Connecticut.

Recently, she told GQ magazine that playing womaniser Don Draper in Mad Men for so many years had left its mark on Jon.

She revealed of the series ending: “The end was of course bittersweet and complicated for Jonny. But I know that when he wrapped the show in LA, in the wee hours of July 3 last year, and then immediately got on a plane to New York to meet me and our dog, Cora, for dinner with a few close friends and to watch the fireworks, he felt a predominant sense of relief. He remarked on the cosmic coincidence of the date: Independence Day. Finally.”
