She's been put on blast for some bizarre antics during a friend's wedding in Italy last weekend, and now, Lindsay Lohan is alleging that her troublesome behaviors during the event were the result of someone drugging her during the festivities.

The actress, who has been known for headline-making bad behavior more than her work over the years, was in attendance for the four-day celebration of her friends Justin Etzin and Lana Zakocela, but reportedly caused a lot of drama with her behaviors at the event.

One of the first things she reportedly did to cause trouble was not pay attention during the actual wedding ceremony -- choosing to focus on herself instead of the bride and groom.

"Lindsay was painting her nails during the ceremony and looking at her phone," sources said.

However, the antics weren't limited to the ceremony and also made their way to the reception, where she allegedly hijacked the DJ booth and continually played the song "The Boy is Mine" by Monica and then freaked out about a fan taking her photo.

She allegedly "got upset when she thought someone took her photo. She was speaking in a British accent, 'Who took the photo? Don't be an idiot,'" the source added.

She also reportedly left early to exhibit more bizarre behaviors-which she claimed were the result of someone 'slipping her a mickey.'

"Lindsay left the reception early," the source said. "She'd gone back to her villa and was running around naked saying she was drugged."

However, reps for the groom have said that none of the allegations are true.

Lohan's attire at the event has also been criticized, after she posted a photo to her Instagram page which showed her wearing a tiara and silver peep-toe pumps -- alongside a gown featuring a white skirt with a slit to show off her legs, and a heavily blinged top.

"Hey you beautiful addict! Don't wear white to someone else's wedding. Stay off those pills and maybe one day you'll get to wear one at your wedding and someone there will wear white too," one fan commented on the photo.
