MARK-PAUL GOSSELAAR, CATRIONA MCGINN ENGAGED

Mark-Paul Gosselaar is taking the plunge -- again!

The 36-year-old actor, whose divorce from wife of 14 years Lisa Ann Russell was finalized in May, proposed to advertising executive Catriona McGinn last week, his rep confirms to Us Weekly.

"She's absolutely gorgeous, she's stunning, and she takes my breath away," Gosselaar told Us at Kiehl's LifeRide for amfAR Block Party in NYC on Saturday. "Catriona's great with my kids. My kids absolutely adore her."
