Nicole Kidman appears on a US magazine cover flaunting what looks like a new pair of oversized lips.

The Australia star is known for her frozen face but has never publically admitted to indulging in a little botox or collagen.

But a recent cover shoot for Parade magazine has captured Nicole striking a pose with what can only be described as a plastic pout.

The new mum's appearance has undergone a drastic transformation in recent years, with her natural red, curly hair and delicate features being replaced by straightened, sun-kissed locks and swollen features.

Speaking to the magazine, Nicole reveals how her marriage to Keith Urban is stronger than ever after they battled his alcohol addiction together.

Keith had better watch out for those lips...
