Beyoncé has fueled rumours she's pregnant.

The 33-year-old songstress already has three-year-old daughter Blue Ivy with husband Jay Z, and there have been whispers lately that their second is on the way. Now she has seemingly perpetuated such talk with a suggestive family Instagram photo.

The image posted by Beyoncé on Sunday features her laying on the beach with a sand sculpture covering her body. Around her stomach area is a large mound, akin to a baby bump.

The hitmaker is smiling in the image, with round sunglasses covering her eyes and the sand reaching all the way to her neck. Blue Ivy sits beside her playing in the sand.

No caption accompanies the photo, but the connotation it carries is a curious one. Many reports of late have claimed Beyoncé is pregnant with she and Jay Z's second child, but the power couple are yet to comment.

The star has noted in the past that she does want to add to their family. She told British newspaper The Mirror about her love for motherhood back in 2013.

'Definitely I would like to have more children. Motherhood has changed everything. You see things a bit differently after you give birth and my biggest job now is to protect my child,' she explained. 'After giving birth there's a moment of rediscovery when you are making sure you still have goals and take care of yourself as a woman.'

The image comes just days after the couple celebrated Blue Ivy's third birthday, treating her to a rainbow cake and a party.
