Mark-paul Gosselaar (Bauer Griffin) Just a few months since they began seeing each other, Mark-Paul Gosselaar is engaged to advertising executive Catriona McGinn.

Gosselaar separated from ex-wife Lisa Ann Russell last summer, and the divorce was finalized in May. He was first spotted out with McGinn in April, and she has even posed for photos with Mark and his two children with Lisa Ann, Michael, 7, and Ava, 5 (see below).

Before news of the engagement was made public, Gosselaar told Us magazine about how much he loved his new lady.

"She's absolutely gorgeous, she's stunning, and she takes my breath away," he said. "Catriona's great with my kids. My kids absolutely adore her."

Mark Paul Gosselaar engaged to Catriona McGinn
Either this relationship has been going on for quite some time (like DURING his marriage to Lisa Ann Russell) or foxy Zack Morris just moves on hella fast.
The guy JUST finalized his divorce from Russell (photo shown above) back in May. I guess it is possible to find love a few months later (I mean, they DO do it on the Bachelorette with a minor success rate), but to get engaged so fast after a disastrous marriage really makes me wonder how long this frolicking has been going on.

Gosselaar is marrying advertising exec Catriona McGinn, People is reporting. And apparently Gosselaar whipped out a FIVE carat cushion-cut diamond ring by Neil Lane.
Neil Lane told People magazine that “He couldn’t wait to propose. He was so excited to have found the woman of his dreams.”
Gosselaar has two kiddos from his previous marriage. From what we know, Mark’s fiancee has not been married before and doesn’t have any children.
