Enjoying a night out on the town,  Lindsay Lohan paid a visit to the famous Roxy Theatre in West Hollywood on Saturday night (September 5).

Wearing a sexy ensemble, the “Mean Girls” starlet was there to catch Benji Madden work the turntables for a packed house over the Labor Day holiday weekend.

Missing the companionship of her ladylove, Samantha Ronson, LiLo was busily tweeting away this morning – expressing her loneliness as a result of Miss Ronson’s absence.

The 23-year-old redheaded beauty kindly wrote, “I am sorry.. smile-early mornings w/out my girl just seem to get the best of me…no fun.”
