The 32-year-old Mean Girls actress and the 38-year-old heiress and former reality star used to hang out and party together on and off from 2004 to 2012. But they have also feuded on and off since 2006, most recently this month when Hilton appeared on Watch What Happens Live With Andy Cohen and called Lohan, "Beyond," "Lame" and "Embarrassing."
The actress' rep later told Us Weekly, "Obviously, Paris needs to feel relevant and is desperate for attention." On Friday night, Lohan responded to Hilton's comments herself with a couple of Instagram posts. One of them contained a black and white photo of the two looking happy while hanging out together at the Happy Birthday Marilyn Monroe auction in Los Angeles in 2005. Lohan tagged Cohen in the pic.
