When in LA, find yourself a star surprise guest. Maren Morris did just that at her Friday night (March 29) show at the Wiltern in Los Angeles, Calif., bringing out pop singer JoJo for two duets.

Morris and JoJo performed the latter's mid-2000s mega-hit "Too Little Too Late" together onstage; readers can see snippets of their performance in the Instagram posts above and below. One of JoJo's biggest singles, the song became a Top 5 hit in the U.S., the UK, Ireland and New Zealand, a Top 10 song in Australia and a Top 30 track in Germany.

"Thanks for blessing us with that voice tonight, my love," Morris writes on Instagram. Adds JoJo, who also performed Morris' song "Common" (originally a duet with Brandi Carlile) with the country star, "Maren you are a total babe. Thank u for having me. Your audience was incredible and you are beyond!"

Morris began her current trek, Girl: The World Tour, in early March. Dates are scheduled in the U.S. and overseas until late May, with a number of festival performances and a string of shows in Australia and New Zealand on Morris' calendar through late August. Cassadee Pope and RaeLynn are Morris' special guests.

Morris released her new single, "Girl," for which her 2019 tour is named, in January. Her sophomore album, also named Girl, dropped in early March.
