Lindsay Lohan is still furious with Dina Lohan for agreeing to participate in 'Celebrity Big Brother'.

The 28-year-old actress is reportedly very embarrassed that her mother is in final negotiations to take part in the upcoming series of the British reality TV show.

A source told America's Star: ''It's a nightmare for Lindsay, who blames her mother for much of her problems and doesn't want to be anywhere near her. Lindsay feels totally alone, and partying is the only way she knows how to deal with her feelings.''

Another source previously claimed that the Hollywood actress ''flipped out and began screaming at her mom, saying she had no right to come to England'' when she first found out Dina had signed on to appear in the show.

Tensions have been running high between the duo since it was reported Dina had been selling her daughter's belongings - including clothing, furniture, and artwork - on the Internet and directly to friends without her permission.

Friends fear the 'Mean Girls' star's life could be about to spiral out of control again.

The insider added: ''Lindsay has been partying nonstop.''
