They say nobody's perfect ... but Bar Refaeli comes pretty darn close.

The blonde bombshell poses in her undergarments for a new Valentine's Day campaign for Passionata.

In the photos, the 27-year-old puts her stunning figure on display, wearing just a bra and panties for the '50s homemaker-inspired shoot.

If wearing Passionata bras and underwear can make us look like that -- we're sold.

The supermodel has been making headlines for more than just her good looks though -- her latest Super Bowl Go Daddy ad has the world buzzing.

In the commercial for company's "Smart Meets Sexy" campaign, Bar plays the sexy "domain" and her nerdy co-star, Jesse Heiman, is the smart Go Daddy engineer.

And yes ... the two tongue wrestle!

Seriously, check out the clip below. The intimate scene reportedly took 45 takes to complete ... and two different versions of the ad have been cut from CBS for being "too indecent."

See for yourselves and sound off below:
