Keanu Reeves and girlfriend Parker Posey have sparked rumours they are expecting their first child together.

The couple – who were first romantically linked in April – were spotted spending more than $1,000 on baby products in exclusive Los Angeles store Petit Tresor.

An onlooker said: "They both looked really happy. They were holding hands and laughing as they walked around the shop. Keanu was picking out lots of different things and seemed really excited."

However, a source close to the pair insists they were buying the products for a friend, and says the monogram on the playmats they purchased does not match either Keanu or Posey's names.

Keanu, 44, hasn't been in a serious relationship since his long-term girlfriend Jennifer Syme was killed in a car accident in April 2001.

Her death came after she gave birth to the couple's stillborn daughter Ava Archer Reeves in December 1999.

Parker has been romantically linked to 'New York' rocker Ryan Adams and writer Thomas Beller. (c) BANG
