Lindsay Lohan traded her usual shopping companion, Samantha Ronson, for her sister as she ran errands around LA yesterday. Even though LL and Sam were spotted together on Wednesday, the rumors are still swirling that they have split up. The latest one is that Lindsay is in denial that Samantha broke up with her and has been spotted spending more time with Sean Penn. The actress is sticking by her story that she's not a single woman yet, so we'll wait to hear it from Lindsay's mouth if it ends up being true. At least she has Ali to cheer her up while things are tough and a new batch of Fornarina ads that show off her modeling side.
