Miley Cyrus and Liam Hemsworth worked on their fitness together in Beverly Hills.

If you didn't already think Miley Cyrus and fiancé Liam Hemsworth were the cutest (and most attractive) couple ever to walk this planet (check out this photo if you need additional evidence), this photo of the couple leaving Pilates may be all the proof we need. How does that saying go? "The couple that stretches together... has better abs and obliques than everyone else"? I think?

The newly blonde "Party In The U.S.A." singer and her beau were snapped leaving a Pilates studio in Beverly Hills together, and we have to give the pair major props. Not just because Pilates is THE HARDEST EFFING THING WE'VE EVER DONE (that one time), but also because seeing your significant other's sweat-drenched armpits and not getting grossed out really means you're in love!

But we're pretty confident that this whole "ready to have a baby quickly" rumor going around about Miley and Liam is completely false. 'Cause if we were ready to pack on pregnancy pounds, there'd be way less painful stretching and a whole lot more stuffing our faces with Cheetos.
