Lindsay Lohan spent an evening flirting with 'Gossip Girl' actor 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 said: "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 pair swapped phone numbers and as well as texting him, Lindsay has also been calling Chace up to four times a day.
The source added: "Everyone on the set of 'Gossip Girl' has been teasing him mercilessly as Lindsay has been calling him three or four times a day and sending provocative text messages."
Chace, 23, is reportedly concerned Samantha, 31, may be angry about the flirty exchanges, and is doing everything he can to ensure he does not see her on the party scene.
The source added to Britain's Daily Mirror newspaper: "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."
