The couple were first spotted together in May but only took their romance public around Lohan's 18th birthday in July. "She is my girl," says Valderrama. "I love her very much. She is a fantastic person and I'm extremely proud of her." The chain-smoking, club-loving pair, who move with a party pack that includes Paris Hilton, Bijou Phillips and Nicole Richie, recently exchanged promise rings—and yes, Mom approves. "Wilmer's a sweetheart," says Dina, 41, a former Radio City Rockette. "He is very protective. He's basically Lindsay's first real boyfriend."
Fortunately for the media, the relationship has not been without drama. Out and about on the L.A. club scene, Lohan and Valderrama have variously been spotted looking passionately in love and tensely not. Acknowledges Dina: "They're going to make their mistakes now. They're living publicly. They're going to have fights. It's normal behavior." For his part, Valderrama says their relationship "is about trust. She's a smart girl. She knows what's good for her."
In November, just weeks after Lohan makes a cameo appearance on Valderrama's show, reps confirm the two have broken up.
