The 'Cool for the Summer' hit-maker, who posed topless on a banana, wearing nothing but a pair of sheer blue underwear and covering her assets, explained that it's a part of life that when people grow old, they change, and there's nothing wrong with it, The Mirror reports.

The 23-year-old singer added that Bieber is a nice guy and is maturing with time.

Lovato, who has been dating actor Wilmer Valderrama for almost five years now, also said she wants a shabby chic outdoor wedding with lights hanging on trees.
