man, i musta picked the wrong guy! it seems american idol judge/billionaire simon cowell has a heart of gold, despite how it may appear on TV. after splitting with longtime girlfriend terri seymour, cowell has quickly moved on!

and oh man, has this new lady hit the jackpot. makeup artist mezhgan hussainy and mr. simon have been in the land of love ever since their start – so much so that simon even popped the question! yup, they’re engaged. awkward much for ex-gf seymour? (they dated for 6 years!)

the future mrs. cowell celebrated her 37th birthday this past week, and no expense was spared. simon has reportedly purchased his lady love a luxury 1954 jaguar convertible priced at over $120,000! and that ain’t it…

“red roses, french lingerie, prada bags, you name it. he gives her something new practically every day. one particularly sweet surprise was private his-and-hers swedish massages in their london hotel room.”

sure, when you make $75 million A YEAR! congratulations mezhgan, you scored big time! see below for some preciousness from the lovebirds – especially simon! – on the tonight show with jay leno.
