-- The "Dancing with the Stars" cast is growing!
Alexa PenaVega and her husband Carlos PenaVega have signed on for the 21st season of the dancing competition, he announced on Instagram.
"Beyond excited that @vegaalexa and I are going to be competing this season on #season21 @dancingabc," he wrote. "Spending 24 hours at @disneyland #disneyland60 to celebrate!!!"
The "Spy Kids" actress, 27, and the singer, 26, were married in January, 2014 after a four-month engagement. They will be competing against one another, as well as Bindi Irwin, Victor Espinoza, Nick Carter and Hayes Grier.
The Big Time Rush musician may have an edge -- he'll likely be getting advice from his former bandmate James Maslow, who placed fourth in season 18 of the ABC show.
"Dancing with the Stars" returns to ABC on Sept. 14.
