Lindsay Lohan has celebrated her 21st birthday with a quiet beach party in Malibu, California.

The young party girl met with friends and family in just a bikini as she kept the party in a nautical theme.

Friends included ex lover CALUM BEST, who joined the party despite having split from the troubled actress last month.

Lindsay had originally planned to hire out the Pure nightclub in Las Vegas for a huge birthday bash, which was also due to be sponsored by a vodka company.

However, Lindsay pulled out following her stint in rehab for drug and alcohol addiction, and opted for a low-key event instead.

Kate Turner, a spokesperson for Pure, said: "Due to the unique circumstances, Lindsay's birthday party at Pure Nightclub has been cancelled. We think the world of her and look forward to working with her in the future."

She added: "We support Lindsay and wish her the best as she is taking care of personal matters at this time."
