Lohan keeps a tight leash on Harry

Lindsay Lohan is a jealous girlfriend who keeps tight wraps on beau Harry Morton, according to several sources. "She flips out if any other girl is around him," says one insider. Another says, "I was at a small party, and she was there with him and like four other girls, and she was really nasty to me. I didn't care - I was with my own boyfriend." And yet another insider says, "When she is not with Harry she constantly texts, emails and calls him. She has to know what he's doing every second of every day. The other day, she was coming to meet him at the Ivy and...his phone was blowing up with her saying, 'I'll be there in four minutes,' 'I'll be there in two minutes, get everyone ready!'"
