Irina Shayk has one very lucky modeling partner in her latest bikini selfie — but it's not boyfriend Bradley Cooper!

The 30-year-old is currently in an undisclosed tropical location for a secret project, but it appears she still found time to have some fun with a new animal friend.

"Double trouble #SelfieTime," Irina captioned the first pic she snapped, along with an emoji of a girl and a donkey.

The model wore no makeup in the flawless pics, and even her hairy partner in crime couldn't steal the spotlight from the Russian beauty.

"When your donkey is done and over your selfies.. ," Irina ended the photo series, showing the animal taking a nap in the grass behind her.
