Actor Lindsay Lohan and pop star Lady Gaga reportedly enjoyed a slumber party at a hotel. The Liz & Dick actor was joined by 26-year-old Gaga at Chateau Marmont hotel and apparently they spent the evening together watching old movies and playing board games, reported Ace Showbiz. “They had dinner in the garden at Chateau, and then Lindsay and Gaga ran upstairs to play dress-up and came down in different outfits,” a source said. Gaga tweeted to Lohan saying, “When you ordered a cucumber and a knife to the bar last night, I thought your were going to perform a vasectomy.” “Skinny snack 1, Lady Gaga hahaha,” Lohan replied back. Gaga also tweeted a photo of a tray with a cucumber with a knife in it and sliced lemons sitting on bar. She captioned the image: “How much could one do with this arrangement!”
