Lindsay Lohan is leaving her party girl days in the past and replacing them with quiet nights in front of the TV.

The Mean Girls star's declaration comes after Lindsay seems to have settled down into a serious relationship with girlfriend Samantha Ronson.

"I watch a lot of TV. More than I've ever watched because I don’t go out every night," she told US TV show Extra in an interview.

Lindsay and Sam only came out just over a month ago but their relationship was kept a 'secret' for months beforehand.

The actress was one of the many stars to make a political impact yesterday, voting for Barack Obama.
