Keifer and Shawna Thompson, better known as husband-wife duo Thompson Square, are getting ready to have another late night in their future!

Earlier this month, the duo graced the stage of 'The Tonight Show With Jay Leno,' and now they are heading to TBS for their debut on 'Conan.'

"Doing 'Leno' was just ridiculous," Keifer, who is clearly still riding high from the experience, tells Taste of Country. "We got to hang out with Christie Brinkley and Aaron Eckhart after the show. It was pretty amazing."

"We were out of town or flying around when it actually aired, so we didn’t get to see it until two or three days later when we got home," adds Shawna. "We sat there with the DVR and kept rewinding it back to when Jay came over and shook our hands. We were like, 'Is that really us?!' It’s the most strange thing ever to see us hanging with Jay Leno!"

Thompson Square are scheduled to appear on 'Conan' on Thursday, March 31, where they will perform their hit single, 'Are You Gonna Kiss Me or Not.' The song is in a steady climb to the top of the charts, this week sitting at No. 3.

"That’s going to be pretty awesome," Keifer says of their 'Conan' appearance. "It’s been a whirlwind for us lately. There is so much going on. Every day something is getting added … it’s awesome. I just could not ask for more."

"We are very blessed right now," agrees Shawna.

Thompson Square's life is about to get even more hectic come summertime when they hit the road with Jason Aldean on his My Kinda Part Tour, also featuring Chris Young, starting July 8. Click here for a list of dates where the tour will be stopping.
