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 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.
