Cher and Florida Georgia Line also scheduled to perform on June 18 finale
Christina Aguilera is returning to "The Voice" sooner than expected.
The "Bionic" singer, who took a break from her coaching duties on the current cycle of the NBC singing competition but will return for its next cycle in the fall, will be back on the show for its season finale June 18.

NBC also said Tuesday that Bruno Mars, Nelly, Pitbull and country duo Florida Georgia Line will also perform during the two-hour finale.
As announced Monday, Cher will also sing during the season send-off, marking her first live television performance in more than a decade.
Though Aguilera co-starred with Cher in the 2010 film "Burlesque," she'll perform on the "Voice" finale with Pitbull, dueting on "Feel This Moment," the most recent single from Pitbull's "Global Warming" album.
Mars will appear via a pre-taped performance of his single "Treasure" that was taped last month, before the death of his mother.
Nelly will join Florida Georgia Line to perform the duo's single "Cruise."
