Heidi Range is expecting her first child with husband Alex Partakis

Sugababes star Heidi Range has confirmed that she's pregnant with her first child.

Singer Heidi, 34, revealed the happy news to HELLO! magazine, adding that she and husband Alex, who married in September last year, are expecting their new arrival in January.

'Our wedding was amazing and then I had hoped I would fall pregnant straight away. But as each month went by I would take a test and I got used to it always being negative,' Heidi explained to the title.

'So when it came back positive it was a shock. Alex was asleep and I came running into the bedroom with the stick, saying, "Is that a cross? Am I pregnant?"'

Heidi said that the pair had moved into a new home around Easter time, after spending two years renovating the property, and believes that her baby was conceived around this time.

'It was like it was meant to be,' she continued. 't was so special that it happened in our first family house together. It's made our home have this lovely feeling about it.'

Heidi chose to break the news to her mother first, and she couldn't contain her excitement at the announcement.

'She started jumping up and down, saying, "Oh, my baby is having a baby!" About five minutes later we were googling prams and nurseries,' Heidi laughed.

'My sister Hayley has already bought name books. They are dying to know whether we are having a girl or a boy so they can start buying clothes.'

Heidi and Alex were reportedly set up by her personal trainer in early 2014, and tied the knot in a stunning Italian ceremony in September 2016.

On the morning of the big day, Heidi tweeted to her fans: 'I'm up & today's the day! Marrying the kindest & most gorgeous man I have ever known, my @alexpartakis. It's like Christmas but better!'
