BlindGossip – Which musical family man is having a kinky affair? He and his wife are on the outs, and he’s totally smitten with a younger sultry vixen. Why? She loves p*rn and experimentation.
SOLVED!
It’s Robin Gibb! Source: BlindGossip
Robin Gibb of BeeGees fame has had an open relationship with his wife for years, but she went ballistic when he fathered a child with a woman half his age. Congrats to Leigh for the correct answer, and thanks for the link with all the sordid details!

I think its Donnie Wahlberg and Aubrey O’day
What about Matthew Broderick? He’s been in musicals, a family man, and SJP’s line is Bitten….play on the word smitten? They were recently having problems cause of the rumor about him and a younger girl…
She’s a very kinky girl sounds like ‘she’s a very freaky girl’ from superfreak.
