Ali Larter just got engaged to longtime boyfriend Hayes MacArthur. We wonder if she used the old whipped cream bikini trick that she used on Paul Walker (and tried on James Van Der Beek) in Varsity Blues to get MacArthur to propose? You may not recognize Hayes MacArthur, but he was in an episode of How I Met Your Mother and The Rock’s The Game Plan. We expected him to look like a Northeastern blueblood with a name like Hayes MacArthur (a last name for a first name and a manly last name). But it turns out that he's sort of your average (by Hollywood standards) sort of big dude. Good work on his part landing Ali Larter, he probably tells people that it's his career role. Tear.
