These supermodels keep getting better with age!

Naomi Campbell took to Instagram on Sunday to share a sexy snapshot with Kate Moss, where the models are armed with giant Super Soaker water guns.

"#theoriginals #copycats @joansmalls @karmen_pedaru #love," she captioned the cute candid.

The 44-year-old beauty is playfully calling out Joan Smalls and Karmen Pedaru for copying her pic with Kate.

Joan shared a gun-toting photo of her own, writing, "Me and K-Money💰#aka @karmen_pedaru taking Ibiza hostage tonight."

We have to admit -- Naomi and Kate look just as hot as these youngsters!

So, how does Campbell maintain her enviable figure?

Naomi credit gyrotonics for helping her tone her body and lengthen her muscles.

"I don't like workouts that make you bulky. This really stretches you," she recently told Oprah.com. "What I like about gyrotonics is you feel like you really elongated yourself for the day ... As we all get older, everything changes and moves, and there's natural ways to exercise. I think it's important, and I think it's something that can help keep things in place."

Her workout routine is certainly paying off!
