The duo – who are "together," a source says in the new issue of PEOPLE – were spotted Wednesday afternoon lunching with Ronson's writer-mom, Ann Dexter-Jones and Lohan's sister Ali, 14, at the Italian restaurant Gino's on Manhattan's Upper East Side.
Throughout the meal, the group engaged in a spirited session of girl talk, the source adds.

Multiple sources tell us the mother is Jaymes Foster, a record producer and Clay's best friend. He lives at her home when he's in L.A.
We're told Foster, who produced several Aiken CDs, is due in August. She's the sister of record mogul David Foster. We're told she's in her late 40's, though we could not confirm her exact age. She divorced a few years back and has no kids. Aiken is 29. We're told Foster was artificially inseminated. But Clay is a lot more than sperm -- we're told he will have an active role in raising the child.

The Canton-based company has abruptly canceled an ad in which the domestic diva wears a scarf that looks like a keffiyeh, a traditional headdress worn by Arab men. Some observers, including ultra-conservative Fox News commentator Michelle Malkin, were so incensed by the ad that there was even talk of a Dunkin’ Donuts boycott.
‘‘The keffiyeh, for the clueless, is the traditional scarf of Arab men that has come to symbolize murderous Palestinian jihad,’’ Malkin yowls in her syndicated column.
‘‘Popularized by Yasser Arafat and a regular adornment of Muslim terrorists appearing in beheading and hostage-taking videos, the apparel has been mainstreamed by both ignorant and not-so-ignorant fashion designers, celebrities, and left-wing icons.’’

Said the suits in a statement: ‘‘In a recent online ad, Rachael Ray is wearing a black-and-white silk scarf with a paisley design. It was selected by her stylist for the advertising shoot. Absolutely no symbolism was intended. However, given the possibility of misperception, we are no longer using the commercial.’’
