Blake Lively and husband Ryan Reynolds have reportedly welcomed their first child to the world.

The former Gossip Girl star, 27, is claimed by the New York Post to have given birth earlier than expected.

But a source told the paper that mother and baby are both healthy - and that she gave birth near the couple's home in Bedford, New York.

A representative for Lively refused to comment on the matter to the paper.

Although she has been on Instagram since she is reported to have given birth, she has just been sharing pictures of her artwork and homewares collection.
