Kiernan Shipka was always destined for the spotlight! 

The "Mad Men" star stopped by Thursday's "Jimmy Kimmel Live" where she opened up about her start in showbiz. 

Check out the clip above to see one of Shipka's first sketches on the late night show! 

The blonde beauty started working with Kimmel on "Jimmy Kimmel Live" when she was just 6-years-old, and Jimmy had a very special treat for the actress. 

"I feel like this is really coming full circle, I found out I booked 'Mad Men' in the 'Jimmy Kimmel' parking lot," the actress told the comedian. 

"We were excited you were coming on, because when you were a kid, we were like 'She's great, we need to use her all the time,'" Kimmel explained, before showing a vintage clip of a very young Shipka impersonating Britney Spears.

In the funny bit, Kiernan plays an aspiring dancer who's been taking tips from Britney ...  as she sports a baby bump and impersonates that infamous umbrella moment.

The 15-year-old beauty sure has come a long ways since her days on "Kimmel" -- what do you think about Kiernan's throwback parody? Tell toofab in the comment section below and check out the gallery to see even more child stars then and now!
