Mark-Paul Gosselaar is a married man -- again!

The Saved By the Bell actor tied the knot with advertising executive Catriona McGinn Saturday, a source confirms to Us Weekly.

"Catriona's absolutely gorgeous. She's stunning," Gosselaar gushed to Us last year. "And she takes my breath away!"

Gosselaar, 38, popped with the question in July 2011 with a 5 carat cushion-cut diamond ring designed by Neil Lane. "He was delightful to work with, it's always a treat to work with a true romantic," Lane told Us at the time.

Gosselaar was previously married to Lisa Ann Russell for 14 years; their divorce was finalized in May 2011. The former couple has two children, Michael, 8, and Ava, 6.

"Catriona's great with my kids," Gosselaar told Us. "My kids absolutely adore her."

In addition to his role as Zack Morris on Saved By the Bell, Gosselaar's other TV credits include NYPD Blue, Raising the Bar and Franklin & Bash.
