Just Jillian, 101

E!

Happy birthday, Jillian Michaels!

The Just Jillian star turns 42 years old today and we wanted to do something special for the fitness phenom in celebration of her special day.

So in honor of Jillian, we put together a gallery of the funniest moments from this season of Just Jillian.

Look back at the time Jillian asked "what the f--k is this?!" and called herself "strong like bull."

Check out the gallery to see all of the most hilarious moments from the show!
