Lindsay Lohan was taken aback when a man was arrested after reportedly pouncing on her.

The Mean Girls actress was leaving a nightclub in Scottsdale, Arizona with her lover Samantha Ronson when the man barged through a wall of security guards and pounced on her.

The 38-year-old man was taken into custody for disorderly conduct and released without charge after several hours.

An onlooker revealed cops questioned Lohan and Ronson after the incident outside the Jackrabbit Supper Club & Lounge, reports the Daily Star.

Lohan had been at the nightclub to support saMAN, who was hosting an event there.

Lindsay Lohan was partying in the DJ booth with girlfriend Sam last night at PURE nightclub in Las Vegas -but it was a mystery man who stole the show as he got freaky dancing with Lohan. The two were very clearly grinding into each other.

Wonder if that made saMANtha jealous!! This is yet another instance of Lindsay flirting with a guy and it gets people talking - is LiLo not as gay as she says she is?

Lindsay Lohan is on the edge and taking chances with her relationship with saMANtha. Lilo apparenty spent an evening putting on the charm in front of Gossip Girl star Chace Crawford and has since sent him several ’steamy’ text messages.

The Mean Girls actress - who is dating DJ Samantha Ronson - met the handsome star at a recent party and allegedly spent the night “throwing herself at him”.

A source revealed: “Lindsay took a real shine to Chace and was pretty much throwing herself at him all night. She was standing in such a way that some part of her body was always touching him - at one point hip to hip.

“She was giving him the filthiest looks, whispering in his ear, and turning everything he said into an innuendo.”

The source added: “Although Lindsay may just be having a laugh and not have any serious amorous intentions, everyone reckons Samantha will go mad when she finds out. As a result Chace has been advised to stay well away from Lindsay and give the couple a very wide berth.”

After years of making people wonder whether she is or not gay, Pink has finally come out in the open. She says that she has experimented on the one-off occasions, but is not a permanent lesbian. Rumors had intensified after her divorce from Motorcross champ Carey Hart, earlier this year.

This is what she had to say:

“I.m not gay so I guess I would not try a relationship with a woman. I didn.t say I haven.t experimented but I love men too much to make it a permanent thing..

Lindsay Lohan and saMANtha are not scared of flaunting their relationship anymore - here they are off vacationing on a beach in Mexico. Lindsay looks hot! No offence to Sam, but I couldn’t have imagined her in a bikini.
