Lindsay Lohan Steps Out with Ali and Sam

Following morning promotional duties alongside her mother Dina, Ali Lohan met up with big sister Lindsay Lohan and her BFF Samantha Ronson for a romp around the Big Apple on Wednesday (May 28).

An eyewitness tells: "(Lindsay) was all smiles and even held her sister's hand in the street as they tried to blend in with the regular NY'ers."

The source adds: "Samantha at times tried to stay a bit separate from the group as they walked across Park Avenue and on the Upper East side on a sunny day in Manhattan."

As for Samantha's stand-offish ways, maybe LiLo's people told the duo to cool things down after the recent rumors claiming that Lindsay has gotten engaged to Ronson, who's openly gay.

Trying to quell the nuptials chatter, Lohan's rep, Leslie Sloane, wrote in an e-mail: "This is gross. She is not a bad girl. Leave her alone."
