Lindsay and Samantha’s relationship has hit a rocky patch, after the DJ got furios and got into a rage when she saw Lindsay flirting with ex-boyfriend Calum Best at a recent night out.

A source reveals, “Sam had had a few cocktails earlier in the evening and was perhaps a little more emotional than usual.

“While she was in the VIP section, Calum went up to Lindsay on the dance floor. Lindsay was lapping up the attention, having a laugh - and a flirt. But Sam saw them and went ballistic.

“She marched over and started pushing the pair, demanding to know what they were doing.”

The fight got so intense with both the girls calling each other names, that finally Calum Best had to intervene and seperate them.

The source adds, “They caused quite a commotion - everyone was staring.

Then it erupted into a catfight, with Sam and Lindsay swearing and screaming like banshees.

“Calum looked mortified then things got nasty and he stepped in to separate them.”

However the girls kissed and made up after they went into their room.
