Kate Hudson Spends Mother's Day with his Son and Her Baby Bump is on show.

Come next year Ryder Robinson will have a new sibling to help him wish Kate Hudson a happy Mother's Day.

But for now the youngster enjoyed his last year as her only child as he spent the U.S. holiday with his mother Kate Hudson.

The pair were spotted hand-in-hand as they arrived at Heathrow Airport in London, perhaps on their way to visit Kate's fiancé Matt Bellamy.
