Alexa Vega is ready to give marriage another go.

The former child star, who hit it big in the "Spy Kids" movies and will appear in "Machete Kills," is set to walk down the aisle for the second time -- this time with Big Time Rush star Carlos Pena, Jr.

Carlos, 24, posted a photo of his brand new fiance, 25, wearing her giant engagement ring -- which appears to have a canary yellow stone. Vega shared a new photo of Pena too, calling him her "fiance."

Vega was previously married to producer Sean Covel from 2010 to 2012. Hopefully this marriage lasts a little longer! 

Congrats to the happy couple!
