Lady Antebellum and Bell Biv DeVoe teamed up during Monday night's (March 6) episode of Jimmy Kimmel Live to perform their hits "Need You Now" and "Poison" as part of Kimmel's Mash Up Monday series.

Readers can press play above to watch the performance by Lady Antebellum and Bell Biv DeVoe, together billed as Lady Antebell Biv DeVoe. The country trio -- dressed in airbrushed denim jackets with "Lady Antebellum" written on them -- open with a slowed-down, soulful few lines of "Poison," lending their signature harmonies to the R&B hit. Bell Biv DeVoe -- wearing similarly airbrushed denim jackets -- join them onstage to kick the song into high gear, then duet with Lady A on "Need You Now."

Released as a single in early 1990, "Poison" became a No. 1 and platinum-selling hit for Bell Biv DeVoe, and one of the most successful singles of the year. "Need You Now," meanwhile, became a No. 1 and multi-platinum-selling single for Lady A following its release in 2009; the song is an ACM, CMA and Grammy Awards winner.

Lady Antebellum's new studio album, Heart Break, is set for release on June 9; the record's first single, "You Look Good," is out now. The trio will kick off their You Look Good World Tour on May 26 in Bakersfield, Calif., with Kelsea Ballerini and Brett Young serving as their opening acts; a list of all of their upcoming shows is available on their website.
