The Loose Women star announced her split from the actor last month and has since confirmed her relationship with toyboy Lincoln Townley.
"Tim's got a new girlfriend, but no one is supposed to know about her," she was overheard telling a friend, according to The People.
"He is fine. I call him four times every day. He is very happy and the kids are absolutely fine."
A friend added that Welch, who won Celebrity Big Brother in January, is "so happy" Healy has found someone.
Welch was recently rumoured to be moving in with Townley while she rehearses for a theatre tour of Steel Magnolias.
