After surviving a string of failed relationships with stars like Wilmer Valderrama and Calum Best, 22-year-old acting vet Lindsay Lohan is hoping her poor judgement when it comes to romance won’t rub off on her younger sister, Ali.

At 15, Ali is ready to start dating and she’s turning to her bisexual big sis for guidance and advice on figuring out the opposite sex.

Good luck with that one, Ali!

An In Touch Weekly informant says: “Ali really looks up to Lindsay and wants to be like her.”

“Lindsay has even been giving her advice about guys and to be careful and not always believe them. She’s teaching her from the mistakes she’s made”
