Gisele Bundchen and Alessandra Ambrosio sizzled on the Brazilian catwalk this weekend.

But there was a surprise guest on the runway with them.

And we bet you can't guess who.

Hollywood star Ashton Kutcher shared the catwalk with the supermodels for the Colcci Autumn/Winter 2011 show at Sao Paulo Fashion Week.

But wife Demi Moore didn't intend to allow Ashton to steal the limelight. Demi walked the red carpet with Ashton and sat front row with daughter Tallulah Willis.

But while Demi can usually hold the limelight to herself, she had little hope of holding anyone's attention with Alessandra and Gisele on the runway.

The pair showed off picture-perfect figures in skimpy creations by Colcci.

Our shrinking self-esteem has never been more grateful for the vast distance between here and Brazil.
