MARLON WAYANS CAUGHT STEAMY, WITH SOMEONE OTHER THEN HIS LIVE IN BABY MAMA IN ST BARTS

Oooh ...so BUSTED! Cheater?... Marlon Wayans might have some explaining to do. The  Wayans brother  has been photographed enjoying the company of a brunette aboard a luxury boat in St Barths - only problem is the mystery lady is not his girlfriend of 12 years.

Did not mind who saw: The 40-year-old star could not keep his hands or his lips off the woman despite being surrounded in guests

Marlon is notoriously private about his personal life, but he and his partner Angelica Zackary have two children together Amai, 12, and Shawn,10. Just last month the comedian confirmed he was with his children's mother - even though the pair live in different homes - on the Wendy Williams show.

'I have two children, a son and a daughter, my son is 10 and my daughter is twelve,' the 40-year-old told host Wendy. '(Their mother is) Japanese and black.' The actor said 'yes' twice when asked if they were still together after 12 years but said they do not live together as 'I like to keep it fresh'.

However, on Monday the Haunted House star was cavorting with a much younger woman on a massive yacht in the tropical waters of the French West Indies.

 The 40-year-old star could not keep his hands or his lips off the stunning woman as they lapped up the sunshine and she showed off her athletic and extremely toned figure in a barely there Missoni print string bikini. 

We got a feeling that the live in is used to this treatment, that's why he keeps her locked up and out of the spotlight.  So disrespectful! Peep Video below of Marlon claiming the Baby mama.  Wow what a difference a couple of weeks make.
