David Beckham's sister Joanne has confirmed she's expecting her first child with ex-Big Brother star Kris Donnelly with a sweet baby bump picture on social media.

Her big brother David already has a brood of four, and now it's time for Joanne to start her own.

Joanne confirmed the news that she'll soon become a mum for the first time with an adorable picture of former Big Brother contestant Kris kissing her baby bump, which she posted on social media.

Captioning the sweet snap with a reference to one of her sister-in-law's most famous songs, she wrote: 'W H E N . T W O . B E C O M E . T H R E E !!! @krissydonners ! If someone would have told us at the start of the year how our lives would change I would never have believed it ...

The couple went public with their relationship earlier this year

The 35 year old went public with her relationship with Kris, who previously dated Hollyoaks actress Jorgie Porter and was a contestant on Big Brother in 2009, in May this year.

It's been an exciting few years for Joanne, who not only announced her relationship and now her pregnancy, but also launched her own luxury concierge business in 2015.

Joanna says she's a 'proud auntie' on her Instagram account

After working as a hairdresser for 16 years, Joanne founded WeAreYourCity with former footballer Jay Smith, in order to plan the social lives of the rich and famous.

Speaking to Business Insider UK about her £4,000-a-year concierge company, she said she wanted to do 'something for herself'.

Congratulations to the happy couple!
