LINDSAY Lohan is going to be a big sister again and she is reportedly not very happy about it.

The starlets father Michael Lohan, 52, is expecting a baby with his on-again, off-again girlfriend Kate Major, 28.

TMZ reports that LiLo is absolutely shocked by the news and was immediately concerned at how Michael could afford to pay for another child after his years of child support battles with her mother Dina Lohan.

Michael and Dina have four children together with rumours that he is also father to a teen girl.

The Mean Girls star is also reportedly upset that she heard about the pregnancy through the media and has yet to receive a call from her father about it.

In another twist, Kate is in the first trimester of her pregnancy but a restraining order she had taken out against Michael was only lifted a few weeks ago.

The couple was formerly engaged but Kate has accused Michael of harassing her and assaulting her in the past.
