Kourtney Kardashian has announced she is expecting her first child with husband Travis Barker.

The 44-year-old reality TV star revealed the news while her Blink-182 drummer husband, 47, performed on stage in LA.

Holding up a huge sign with the words “Travis I’m pregnant” the star beamed and jumped up and down from the crowd.

A video, posted to the star’s Instagram account, shows Barker making his way off-stage to embrace his wife.

The pair married in May last year.

They held a small ceremony in California before a luxurious weekend celebration at L’Olivetta, a villa owned by Dolce & Gabbana in Portofino, Italy, surrounded by their closest friends and family.

The reception was hosted at a nearby 16th-century castle, Castello Brown.

The pair, dubbed “Kravis”, both have children from previous marriages but have publicly spoken about wanting a child together on the family’s reality show.

Kardashian shares three children – Mason, 13, Penelope, 10, and Reign, eight – with ex-boyfriend and Keeping Up With The Kardashians co-star, Scott Disick.
