This is no Mindfreak! Illusionist Criss Angel proposed to his girlfriend Sandra Gonzalez while vacationing in Cabo San Lucas, Mexico on Sept. 7. Angel's rep confirmed to E! News, stating that the couple -- who met four years ago on the set of his A&E series Mindfreak -- is "ecstatic" about their engagement. The Las Vegas headliner, 43, popped the question with a 5-carat princess-cut diamond on a platinum band that he codesigned with New York jeweler Idayne Kaye. As the good news spread, Angel twittered his fans: "Sandra & I thank u 4the beautiful thoughts, wishes&kind words. We have never been happier -thanx2 all of u 4making this time so special 4us."
