Kate Middleton's 'hot' brother James Middleton has everyone swooning after sharing private photos ...

Unlike Kate and Pippa Middleton, James has mostly kept out of the public eye – until now.

The Duchess of Cambridge’s younger has sent Royal fans into a frenzy after he made his private Instagram account available for public viewing.

The 31-year-old has now been dubbed as "hot" by his new admirers who are swooning over his photos.

Along with numerous shirtless snaps, James shared several pictures of his beloved "ever-growing pack" of pups.

We can’t get enough!
