A Republican staffer got into a tussle with Lindsay Lohan after partying with the star in Manhattan last night, the New York Daily News reports. Christian LaBella, who works for Illinois Rep. John Shimkus, was accused of attacking Lohan after she found pictures of herself on his phone, according to the paper:

After the club closed, the actress and LaBella wound up back in her room at the W with other friends, including celebrity booker Claus Hjelmbak.

At about 6 a.m., she took LaBella’s cellphone and got upset after discovering pictures of herself, taken earlier in the evening, police sources said.

LaBella demanded she return the phone, but Lohan balked — and told cops he threw her down on the bed and scratched her.

She ran out of the 15th floor room and scurried down several flights of stairs, with Hjelmbak in tow.

When the “Mean Girls” star and her hunky pal began walking back up the stairs, they again encountered LaBella, sources said.

She claimed that he choked her from behind and threw her to the floor before Hjelmbak yanked him away, cops said. Lohan pulled the fire alarm for help as he fled, police said.
