Kelly Rowland has fuelled speculation she is expecting a baby boy.

The 'Kisses Down Low' singer is pregnant with her first child with husband Tim Witherspoon - who she married in May - and was seen browsing for blue onesies at baby supply store Juvenile Shop in Sherman Oaks, California recently.

According to E! News an eye-witness revealed that Kelly was cooing over the tiny boys' clothing and reportedly said: ''Oh my god, this is so little ... this is so cute!''

She is also said to have registered for a Ferrari F1 baby walker, a Skip Hop Pronto! changing station, a Nuna travel crib and plenty of post-pregnancy shape wear from Belly Bandit.

While Kelly hasn't confirmed the gender of her baby, her former Destiny's Child bandmate Michelle Williams had previously sparked speculation her friend is having a boy.

She previously said: ''I'm so happy that I have another nephew coming to babysit for a few hours and give back to its rightful owners.''

And it sounds like Kelly is taking to pregnancy well, as Michelle added: ''She just looks so wonderful, I'm so happy for her.''
