Carlos Pena Jr. of Big Time Rush is off the market. The singer, 24, is engaged to actress Alexa Vega of the 'Spy Kids' film franchise. It is rumored that the two have been engaged since August, which is their shared birthday month. What a way to celebrate.

His bday is Aug. 15 and hers is Aug. 27, for those keeping score at home.

This will be Pena's first walk down the aisle and the second for Vega, 25, who was married to film producer Sean Coviel. They divorced in 2012 after marrying in 2010.

The couple is clearly in love. Just check their Instagram photos for evidence of their happiness and joy. We're stoked for 'em.

She refers to him as "fiancé" in one HAWT (and shirtless) photo she shared. He also calls her "wifey" in a caption. Sorry, Rushers. Pena is all hers now! But be happy for him. He deserves it.

See the ring.

Here's where he calls her wifey. Aw!!
