We all know how good celebrity relationships can look, but have you ever wondered how good they smell?

Khloe Kardashian and hubby Lamar Odom are now answering that age-old question with a half-naked commercial promoting the launch of their new unisex scent.

Just in time for Valentine's Day, the couple, who have been the picture of wedded bliss since their 2009 nuptials, are releasing their first fragrance, called -- in case there were any doubts about the strength of their union -- Unbreakable.

The scent hits stores Feb. 12.
