Demi Moore is so youthful!

ONE is nearly 50, while the other turns 17 next week - but DEMI MOORE and daughter TALLULAH WILLIS could easily pass for sisters.

The stunning mum, now 48, looked defiantly youthful as she watched the Colcci catwalk show at the Sao Paulo Fashion Week with her youngest.

And she glowed with pride as the guy who keeps her feeling half her age, 32-year-old hubby ASHTON KUTCHER, turned his hand to a spot of modelling.

He took to the runway wearing a grey leather jacket, baggy grey T-shirt and jeans for the Brazilian designer.

Earlier he Tweeted in the local lingo: "Estou pronto para o Brasil. Brazil esta pronto para mim?" meaning "I`m ready for Brazil. Is Brazil ready for me?"

Seeing your man surrounded by a host of supermodels, including GISELE BUNDCHEN and ALESSANDRA AMBROSIO, might cause a pang of jealousy for most women.

But Demi is confident with her body and even posted a picture of herself in a bikini on Twitter recently.

Despite her enviable curves, she recently claimed that she only got the body she craved after she stopped obsessing about it.

The Striptease star said: "I had an extreme obsession with my body. I made it a measure of my own value.

"I tried to dominate it, which I did, and I changed it multiple times over. But it never lasted and ultimately it didn`t bring me anything but temporary happiness.

"Does being thin resolve anything? No. The irony is that when I abandoned that desire to dominate my body, it actually became the body that I`d always wanted.
