The deal would help Swift, 25, and Harris, 31, cement their status as the highest paid couple in music.
Taylor Swift and DJ-producer Calvin Harris have been offered $10 million to pose for an underwear advertisement together.
Bosses of luxury brand Armani are reportedly eager to have the A-list couple front a new ad campaign together, following the success of Harris' recent shoots as the male face of the luxury briefs, reports femalefirst.co.uk.
It is said that this step has been taken following David and Victoria Beckham's intimate shoot for Armani in 2009.
"Armani bosses reckon Taylor and Calvin could emulate the success of the David and Victoria adverts," a source told the Daily Star newspaper. "The Taylor offer is initially around the $10 million mark but that sum could then triple with global promotion if the campaign is successful. Taylor and Calvin are the hottest thing on the planet right now. Calvin's adverts have done really well and helped the brand reach a different audience," the source added.
The deal would help Swift, 25, and Harris, 31, cement their status as the highest paid couple in music. The two are estimated to have a combined net worth of $146 million.
