Lindsay Lohan Instagram post shows the star in a skimpy bikini selfie while vacationing in Ibiza this week.

The Mean Girls star had her face covered by her cell, but you can clearly see her figure and her belly button ring. She also earlier posted several more shots from her day's festivities, including a photo with two guy friends that she captioned, "Be happy and healthy. It's possible." Another post showed her friends throwing up their hands while hanging out in the ocean, captioning the shot, "Happiness is key. Live. Laugh. Love."

Speaking of pics, LiLo was also photographed days before giving Ibiza beachgoers a slight of a lot more side boobs than intended while wearing a bright yellow bathing suit while she jet skied during her Spanish vacay Wednesday.

The actress will soon have to return to London to start rehearsals for her upcoming performance on the West End stage. The former child star is set to make her live theatre debut in David Mamet's Speed The Plow beginning on September 24th.

Lindsay is also planning to write her autobiography and has reportedly held a string of meetings with publishing houses to discuss penning a tell-all book, and promised not to hold back on any detail, including the truth about an alleged list of her famous lovers which was leaked earlier this year and mentioned the likes of Colin Farrell, Justin Timberlake, James Franco and The Wanted's Max George.

"Lindsay held meetings at major publishing houses in London recently - and the stories she promised the literary agents made their jaws drop," a source said. "She's prepared to put everything out there and has already proved she's not shy with the list of men she claims to have slept with."

"Lindsay is now looking for a ghost writer. It may seem unlikely, but she thinks she's in with a shot of getting EL James to work on it - they met recently at [London nightspot] Chiltern Firehouse and got on well. Another pie in the sky idea was that she might persuade JK Rowling to work with her."
