Lindsay Lohan and Samantha Ronson have had another lover’s tiff. This time it’s over one of Lindsay’s former boyfriends – something that’s been a long-standing issue between the pair. According to rumors, Samantha gets excessively jealous whenever an old flame is around. This could be because she doesn’t like reminders that Lindsay used to be with guys, or because she flat out doesn’t like the thought of her girlfriend having been with anyone else. Most of us are no strangers to the latter.

Lindsay and Samantha were at a London club when legendary British playboy (and Lohan ex) Calum Best showed up. And then drama and chaos ensued.

Head in her hands, a glum faced Lindsay Lohan looked like the string of late nights were finally getting to her last night. The actress was left sitting alone in her limousine after an apparent lover’s tiff with girlfriend Sam Ronson. Perhaps the sour mood between the two was caused by the surprise appearance of Lindsay’s former lover Calum Best.

The model turned up in London club Boujis, bumping into his ex-lover for the second time since she arrived in the UK a week ago. His appearance may not have gone down well as Ronson is said to get jealous of Lindsay’s former male lovers.

Lindsay went to the couple’s limousine at 3.45am, but was left waiting for Sam for ten minutes. When they arrived back at their hotel onlookers said British girl Sam stormed out of their Maybach limousine and went inside, leaving Lindsay sitting alone.

Earlier in the evening Sam had hit the decks at another London club – Mahiki. Meanwhile back at Boujis model Best left with some friends and a mystery blonde. Last week he made a surprise appearance at Chinawhite but Lindsay was having none of it, and did her best to avoid him all night. An insider said: ‘Lindsay was horrified when she found out Calum was there and refused to talk to him. Samantha gets jealous of her former male lovers, and Lindsay didn’t want to upset her.’

It doesn’t sound like Lindsay did anything wrong. Wow, there’s a sentence I’ve never said. Normally you can clearly list all the mistakes Lohan has made on any given day. But it seems like the big problem was that Calum Best still exists and is prone to go places. Can’t really blame Lohan for that.

It’s definitely awkward running into an ex, and it doesn’t sound like they’re on friendly terms. But it’s pretty clear Lindsay generally stayed away from him – it’s not like Samantha caught them making out in the bathroom or anything. Presumably. The whole thing sounds sort of overblown. Lindsay loves her drama though, and when she’s in a fairly stable relationship she’s got to take what she can get.
