There's never a dull moment when Lindsay Lohan's around, is there? The actress/ model/ designer/ shagger of Calum Best is currently having what was supposed to be a nice relaxing holiday with her sister Ali in St Barths, but the other night it all got a bit nasty when some random man tried to put the moves on. According to onlookers, Lindsay repeatedly asked one young man in a nightclub to leave her sister Ali alone, launching into a rage when he didn't and punching him "viciously". Ooer! Thankfully the star's bodyguards (we always imagine Kevin Costner when we hear that word, don't you?) soon arrived to break things up, and Ali returned back to the luxury yacht where the famous sisters are staying. The next morning, rather bizarrely, both Lindsay and Ali were pictured laughing and crying into their mobile phones. God only knows what that was all about. One thing's for sure, we won't be heading over for a chat with Lohan if we ever spot her in a club...
