WILL LINDSAY LOHAN'S NEW LOVE KEEP HER SOBER?

When Lindsay Lohan checked out of Cirque lodge rehab center on October 5, she left with a newfound strength in her sobriety and a new boyfriend, fellow rehab graduate Riley Giles.

"We started out as friends," explains Lindsay, who sat down for an exclusive interview with In Touch in Utah. "We met about two months ago while doing activities at Cirque. We both enjoyed rock climbing," she says.

Riley, who is staying in Utah, had been dating a girl named Bree Tierney when he met Lindsay, but he denies their breakup had anything to do with the star. "I broke up with Bree a week before I started dating Lindsay," Riley, 25, tells In Touch. "We had dated for almost two years, but it's not like we were engaged or anything."

One of the things Lindsay appreciates about Riley most is that he isn’t affected by Hollywood. “He finds it all very funny,� says Lindsay. “That’s what I love about him. He has a good sense of humor.�
