So, that's what they were up to!
Back in early February, Ryan Lochte uploaded an Instagram photo on set with Ireland Baldwin, gushing: "She's a sweetheart." The 18-year-old returned the favor by sharing the same shot with the caption: "Kind of an amazing day shooting with @ryanlochte." At the time the duo didn't dish what they were working on but now two months later we finally found out.
The pair were modeling for Calvin Klein's latest White Label "American Icons" campaign for Macy's. And of course, being that this is an Olympic swimmer and a surfer, the twosome posed in swimwear in additon to the classic summer duds (see below).
This is Ryan's second swimwear campaign of 2014. The 29-year-old is also the face (well, body really) for Speedo. Ireland, on the other hand, made her modeling debut with a bikini editorial in the New York Post. She's also flaunted a white hot two-piece on the cover of Beach magazine last June.
There's really no point in asking who models swimwear best here—it's clearly a tie. Everybody wins!
