Morrow, who played Nora Dershlit, was a blushing bride in white lace over the New Year's weekend as seen in friend and fellow actress Vanessa Marano's Instagram post.
"The BEST wedding ever! #weddings," the Switched At Birth star captioned her photo posing with Morrow and sister Laura Marano.
Rowley, 37, played Lewbert in the Nickelodeon series from 2007 to 2012. The actor was also featured in Coyote Ugly and a few episodes of Key & Peele.
The wedding reception appeared to be a great time as Marano shared another smiley photo with her sibling, who stars in Disney Channel's Austin & Ally.
Back in November, another iCarly star tied the knot. Nathan Kress a.k.a. Freddie Benson wed his longtime love London Elise Moore with former costars Miranda Cosgrove, Jennette McCurdy and Jerry Trainor all in attendance.
