Despite hitting the town Wednesday night now that her house arrest has ended, Lindsay Lohan is planning a low-key birthday celebration this weekend.

The troubled starlet turns 25, on Saturday, July 2 and RadarOnline.com has learned that she is not going to be having her birthday party at a Hampton’s night club as previously arranged.

“Lindsay’s decided to lay low on her birthday,” a source close to the actress told RadarOnline.com.  “She wants to get as many hours of her community service done as possible because she couldn’t do any while she was under house arrest.”
