TV presenter Helen Skelton reveals she is pregnant with her second child

TV host Helen Skelton is pregnant with her second child.

The ex-Blue Peter presenter, 33, announced on Twitter that her family of three is set to become four, saying that she feels "blessed".

Skelton, who covered the Olympics in Rio over the summer, has a son, Ernie, aged one-and-a-half.

She and her rugby player husband, Richie Myler, were married in 2013.

Skelton posted pictures on Twitter showing her young son holding a board with the words "ready for my partner in crime".

She captioned the image: "Three getting set to become four. New baby. Feeling blessed."

The baby is due in spring next year.

Skelton recently told how she still manages to fit in her love of yoga around her son.

"I do it when Ernie wakes up at all sorts of hours and Ernie is already joining in. We call him Yogi Baby - he gets into a Downward Dog and shakes a leg - it's so cute!" she said.
