Grown-up "Spy Kids" star Alexa Vega has married Big Time Rush singer Carlos Pena Jr.
A representative for the couple confirmed to Us Weekly Sunday that Vega, 25, and Pena, 24, were wed Saturday in Mexico. This is Pena's first marriage and Vega's second; the actress, who recently appeared in "Machete Kills," is divorced from "Napoleon Dynamite" producer Sean Covel, 37.
On Saturday, Vega tweeted, "Wow . . . I'm getting excited nervous!!!! Ahhhh!!! #CountDownToAisle." She followed this Sunday with a tweet reading, "Mrs. PENAVEGA."
Pena on Friday posted an Instagram photo of an oceanside resort, caption, "YES!!! I can't wait for tomorrow. #lex&loswedding good night!"
Vega and Pena -- whose boy band was formed in conjunction with the 2009-2013 Nickelodeon series "Big Time Rush," which featured a fictionalized version having Hollywood misadventures -- became engaged in September after dating since 2012. Covel, Vega's ex-husband tweeted his congratulations at the time, adding, "May your days be happy, lives be long, and your children, somehow, be tall."
Vega late Friday tweeted a popular Biblical passage often used in marriage ceremonies: "And now these three remain: faith, hope and love. But the greatest of these is love." Vega and Daryl Sabara starred as siblings Carmen and Juni Cortez, the children of secret agents, in the four 2001-2011 "Spy Kids," all directed by "Machete Kills" helmer Robert Rodriguez.
