Lindsay Lohan's birthday barbeque

Jul 4, 2007, 8:00 GMT

Lindsay Lohan celebrated her 21st birthday at her rented Malibu beach house.

The 'Mean Girls' actress, who was casually dressed in a stripy bikini, hosted a barbeque for close friends and family on Monday afternoon (02.07.07).

Lindsay invited her former lover Calum Best, her mother Dina - who arrived carrying a red Cartier bag - her 11-year-old brother Dakota and 13-year-old sister Ali.

Dina told Us Weekly magazine: "I can't believe she's 21. We're all so proud of how hard she's been working to get better."

Lindsay - who is currently being treated in nearby Promises rehab centre for alcoholism - ordered an ice cream birthday cake because it reminded her of her childhood and guests stuck to non-alcoholic drinks.

The patio area was decorated with white candles, hammocks, large umbrellas and sofas.

Guests played volleyball and danced to Lindsay's favourite tunes - including Beyoncé Knowles' hit track 'Irreplaceable' and Rihanna's 'Umbrella' - played by Lindsay's close friend DJ Samantha Ronson.

Lindsay, who spent the afternoon playing beach ball with her siblings, received a series of presents, including blue Louis Vuitton shoes, a skull necklace and a beach cruiser bike.

The flame-haired actress kept paparazzi waiting outside happy by sending them five cheese and pepperoni pizzas.

Lindsay gave each of her guests a visor with her initials emblazoned across it as they left the bash.
