Miranda Kerr wants to ''enjoy'' her body ''while it lasts.''

The former Victoria's Secret model - who has three-year-old son Flynn with ex-husband Orlando Bloom - says she is comfortable stripping down to her underwear because she ''loves'' her figure and while she would love to have larger breasts, she is happy to flaunt her toned physique while she is still young.

Speaking in the May issue of Britain's GQ magazine, Miranda said: ''I won't have a body like this forever so I may as well enjoy it while it lasts. I love my body, look after it and enjoy all the changes it goes through.

''I loved having a bigger chest while pregnant and I'm lucky to have a small frame. I'm a healthy juicy person.''

However, Miranda, 30, does admit that her figure has become noticeably less toned now that she is having less sex since splitting with Orlando last year.

She explained: ''One thing I've noticed is now that I'm having less sex my body isn't as toned. The more sex I have, the more defined my arms and stomach get. Orlando and I always had great chemistry.''

Miranda believes splitting from her spouse will benefit their son.

She added: ''Two happy parents are better than two unhappy parents.''
