Spot the baby bump: Kelly Brook looks as trim as ever in a shot for a new Reebok campaign, taken just days before she announced her pregnancy. She wears a blue crop top and white jogging bottoms, as well as Reebok's TrainTone trainers


She announced earlier this week that she is expecting a baby with her former rugby player boyfriend Thom Evans.

But svelte Kelly Brook looks as trim as ever in a shot from the new Reebok campaign, taken just days before she revealed her happy news.

Wearing a blue crop top and white jogging bottoms, there is only the tiniest hint of a baby bump as Kelly swings expertly from a pair of hanging hoops on the beach.

And perhaps the only indication that Kelly was keeping a secret was the broad smile and thrilled expression she sported for the shots.

Kelly, 31, announced on her Twitter page at the beginning of the week that she and Thom, who have been dating for just over three months, are expecting a little girl together.

She tweeted: 'Thom and I are happy to announce we are expecting a baby girl. We are delighted XXXXX'

A clearly thrilled Kelly later tweeted: 'Thank you for all your lovely messages, I am so excited. X'


Now she's blooming: But Kelly was seen earlier this week looking curvier as she headed out in West Hollywood


A source close to the couple confirmed to MailOnline that Kelly has now had her three-month scan and that both baby and mother are healthy.

Kelly's mother Sandra later said the model is 'unbelievably happy', and told her parents the news at Christmas.

Sandra told the Daily Mirror: 'We’ve known for a long time. Kelly phoned from America just before Christmas. She was unbelievably happy. It’s lovely, we are thrilled.'

She added: 'Thom’s great. They’re very sweet together and make a lovely couple.'


Expectant parents: The little girl will be the first child for both Kelly and boyfriend Thom Evans


Thom and Kelly were first seen together during Kelly's London birthday celebrations in late November last year at The Dorchester, Mahiki and the May Fair Hotel.

Kent-born Kelly has been living and working in Los Angeles since the start of the year, and has completed a number of modelling assignments and campaigns, including her swimwear range for New Look and her collaboration with Reebok.

Former Scotland international star Thom is a former teammate of Kelly's ex Danny Cipriani.

He joined Kelly in the U.S. shortly after they met and has been taking acting classes.
