Yes, she is the sister of that Kimmel, but Jill has a refreshing style of comedy all her own. The charismatic comedian finds absurdity in the everyday frustrations of being a mom, dealing with office politics and confronting the unexpected pitfalls of losing weight. Comedy is in Jill Kimmel's DNA. You do not have to go far to prove it, given her natural ease on stage as she delivers humor that is both self-deprecating and universally relatable. She also happens to be the kid sister of another funny star late night talk show host Jimmy Kimmel. Still, it took her over 35 years to step onto the comedy stage for the first time.
