The 27-year-old actor tied the knot with ex-Miss Delaware, Maria Cahill, on Friday, and Gomez along with the rest of the Russo family attended the soiree.

“Very much in my feelings about my big brother getting married. Even though we for sure knew it would be him first. May God bless you and your beautiful wife Henrie!” the pop star captioned a series of group shots.

The Wizards of Waverly Place co-stars appeared on the hit Disney Channel comedy from 2007 to 2012.

For her TV bro’s big day, Gomez rocked a garnet-colored cutout dress with nude heels, pulling her hair back in braids. She was joined by Waverly Place co-stars Jake T. Austin, Jennifer Stone, Maria Canals-Barrera, and David DeLuise.

The group posed for several photos with the bride and groom and had lots of fun goofing off in the photo booth at the reception.
