Lindsay & Sam: A Mom's Worry

Amid rumors of a recent tiff, lovebirds Lindsay Lohan, 22, and Samantha Ronson, 31, were all smiles for the camera during a recent trip to Tokyo where Lindsay is collaborating with Sam's twin sister and fashion designer, Charlotte Ronson, on Charlotte Hearts Lindsay Lohan, a limited edition handbag and charm line.

But there's one person who's concerned that the media attention may be too much for the young couple. Samantha's mom, Ann Dexter-Jones, says dealing with the gossip is harder for Lindz and Sam than people think. "It makes it very hard for them. You can't have a good ol' argument and nobody cares," Ann told OK! at the Oct. 21 Chanel Mobile art exhibit opening in NYC.

Ann says it's not easy watching her daughter be in one of the most talked-about romances in Hollywood. "I'm naturally concerned," she told OK!, but adds, "Samantha can handle it."

Meanwhile, Lindsay's mom, Dina Lohan, recently blasted rumors claiming her daughter's six-episode guest spot on Ugly Betty was cut short due to tension between Lindz and Betty star America Ferrera.

"It was just silly. America's a doll," Dina said. And as for rumors of Lindsay's diva-like behavior on set, Dina explains, "They said Lindsay brought a posse. It was my mother and myself and Ali Lohan. It was not a posse."
