Samantha Ronson has announced her engagement to Lindsay Lohan. The DJ has let slip the couple are planning to marry by the end of the year after making the commitment.

Samantha, 31, let slip her happy news while DJing at exclusive Hollywood hotel Chateau Marmont.

Lindsay Lohan has confessed she "loves" Samantha Ronson. The "Mean Girls" actress - who has so far refused to confirm she is dating the New York DJ - declared she is "smitten" with the blonde star.

Writing on her official MySpace blog, Lindsay puts her mood as "smitten".

And it keeps getting nastier. Lindsay Lohan's estranged dad Michael is planning a one-hour TV special to expose ex-wife Dina's "lies," he reveals.

He tells TVGuide.com, "I'm going to do a one-hour special. Everyone is going to hear everything for themselves."

Lindsay Lohan's grandfather died Thursday. The "Mean Girls" star's father Michael confirmed the death of his dad Richard - who had been suffering from terminal colon cancer - but revealed he is unsure whether the 23-year-old actress will attend the funeral following the pair's public war of words.

Michael told America's OK! magazine: "My father just, literally, died in my arms. I notified all my kids and my lawyer notified my ex-wife Dina's attorney. Let's see if she has the decency and respect to bring my kids to the wake and funeral."

Michael Lohan would "sacrifice" his life to get rid of his daughter Lindsay's girlfriend Samantha Ronson.

Michael - who has never made a secret of his dislike of Lindsay's DJ lover - insists Samantha is "a drug" for Lindsay, who sought treatment in a rehabilitation clinic last year, and he would do anything to separate the couple.
