Lindsay Lohan got an early start to her weekend aboard a luxury yacht off the coast of Capri, Italy, on Friday. Donning a multicolored bikini, the actress scored some rays and took a dip in the ocean with her sister, Ali Lohan, who — believe it or not! — is already 20 years old. The sisterly bonding comes during a break from Lindsay's hectic rehearsal schedule for her London stage debut in Speed-the-Plow. Lindsay has a long and grueling road ahead of her before she starts performing in front of live audiences in September, but the actress has assured everyone she's not going to need sick days. "That's not on the cards. It's not," she told BBC in a recent interview. "I'm at a place in my life where I like the commitment. I'm looking forward to that part of it." As Lindsay works hard on the next chapter of her career, the star's attorneys are moving forward with a lawsuit against the makers of Grand Theft Auto, whom Lindsay has accused of using her image in their latest video game without her permission.
