Seann William Scott feels ''lucky'' to have found his fiancee.

The 'American Reunion' actor got engaged to Victoria's Secret model Lindsay Frimodt on Valentine's Day (14.02.12) but says he has no idea how he convinced her to marry him.

Seann - who is famed for his role as womanising, sex-obsessed Steve Stifler in the 'American Pie' movies - told E! Online: ''I am engaged. Thank you.

''I don't know how (I got her to agree). She hadn't seen 'American Pie', thank god. Otherwise, I probably wouldn't be engaged.''

''I'm just really lucky.''

Since being with Lindsay, Seann has really tried to distance himself from his alter-ego.

He recently said: ''I have a girl in my life. I was never really able to take advantage of being an actor, because I was always too shy to talk to girls.''

Last year, Seann - who has previously been romantically linked to actresses Jaime King and January Jones - voluntarily admitted himself to rehab last year for ''health and personal issues.''

A source said at the time: ''He completed the 30 days successfully - he's doing great. Seann dealt with an issue and hopefully he can do 'American Reunion' and re-energise his career.''
