Hanging out with fellow celebs can be fun, but nothing really beats sharing the good times with someone closer. For Lindsay Lohan and Rumer Willis that meant taking their sister along with them on a night out this week.
Lindsay's closeness to her younger sibling was eveident as she planted a kiss on Ali's cheek as the pair arrived at the launch of an internet TV show in LA. Fifteen-year-old Ali has been Lindsay's rock since the Mean Girls actress' relationship with DJ Samantha Ronson came to an end last month.
Ali - a teen model and TV personality - and her 22-year-old sister have been spending increasing amounts of time together. They recently returned from a surfing holiday together in Hawaii, and have been spotted out and about in Hollywood in each other's company.
They weren't the only Tinseltown siblings in the spotlight this week. There was an introduction to the red carpet scene for Scout LaRue Willis from big sister Rumer, 20, who took her raven-haired sister to a 'Young Hollywood' party.
Seventeen-year-old Scout is often seen at social events with the girls' parents Demi Moore and Bruce Willis, and has recently started to follow her big sister into the limelight.
In November she made her debut at one of Europe's most glamorous balls, the Haute Couture Bal des Debutants in Paris' lavish Hotel de Crillon.
