Debbie Rowe and Mark Lester, the British actor who claims to be the biological father of Michael Jackson’s first two children -- Prince and Paris -- are currently engaged in a war of words on Twitter, after the actor expressed concerns over Paris’ mental health.

Paris is currently undergoing treatment at an unknown facility after being released from UCLA Medical Center after a failed suicide bid on June 5. And, on July 25, Lester tweeted a message to Rowe, the biological mother of Prince and Paris, stating that they should talk about Paris’ future.

“Hi Debbie I think we need to talk for the good of Paris. We have strong family ties here it can only be for the best,” Lester tweeted to Rowe, to which she replied, “Why don't you go to hell.”

Rowe followed it up with another message asking him to stay away from her and her children.

Days after Paris’ failed suicide bid, British tabloid Mirror reported that just before he died, Jackson had confessed that Lester was the biological father of his eldest two children.

Jackson reportedly made this admission to Jason Pfeiffer, a friend of the late singer.

“One day as we talked about his children and Debbie Rowe, he just came out and said that his children were actually fathered by Mark,” Pfeiffer told Mirror.

“Michael felt Mark was one of his closest friends. He said he was a great actor and very good man. He mentioned that he had taken several people’s sperm and decided on Mark.”

Lester, too, spoke about his ties with the Jackson family in a recent interview and said that Paris could visit him if she ever decides to visit the UK, adding that it would be a pleasure to get to know her.
