In honor of our 13th season (!), we're asking some of our guests what they would say to their 13-year-old selves. Rach couldn't figure out exactly what she'd say to herself at age 13, but she knows she'd tell her 14-year-old self not to take that job as a dish machine operator.
"Worst summer of my life!" she joked.
We couldn't resist posing the question to host of "The Talk" (and the original matriarch of reality TV) Sharon Osbourne. In a letter to her 13-year-old self, Sharon started with one very important lesson: "Be quiet and listen to other people."
She also served up some harsh (but very funny) truths to her teenage self, informing herself that she wouldn't be a ballerina and she DEFINITELY wouldn't marry her crush, John Lennon.
"We had the same birthday," Sharon told Rach, "and I thought, 'this is it, it’s meant to be!'"
We wonder what her famous musician husband, Ozzy, has to say about this!
