Michael Lohan's fiancée regrets claiming he threatened to kill her.

Kate Major accused Michael, who is 'Mean Girls' star Lindsay Lohan's father, of having a knife and trying to break down her locked bedroom door at their home in Florida on Monday night (17.02.14) in a serious of alarming messages on Twitter, and also expressed her fears to police officers, but revoked her original claims after deleting the tweets.

In a statement on Tuesday (18.02.14), she said: ''I regretfully tweeted while my emotions were high that I was being threatened by Michael with a knife; this was not the case. I made a lot of statements on Twitter that were merely out of fear that he was going to take my son from me. Please respect our privacy through this difficult time.''

Kate's comments came shortly after Michael, 53, insisted he was only trying to protect their 13-month-old son, Landon and also claimed he called the police to their home in a bid to prove Kate, 30, ''lied.''

He said: ''My son Landon and nanny are with me. Kate's been having a lot of problems lately with her drinking and pill use and after catching her drinking again tonight, I threatened to take my son away from her, she started this whole thing on Twitter.''

He added: ''I actually had my neighbour over who is a sheriff, but after hearing of Kate's sick tweets, I called the police to prove she lied. Soon after they came, they realised she lied they left.''

Lindsay's mother Dina Lohan, 51, previously accused Michael of abusing her during their 20-year marriage, but he vehemently denied the allegations.
