Cassie could be expecting

Diddy's long-term girlfriend Cassie has sparked pregnancy rumours after she posted pictures of herself with a fuller face and a bulging belly on Instagram.

Eagle-eyed fans began to question whether she was expecting when she uploaded the black and white photo of herself sporting blonde highlights and hoop earrings.

But within minutes she took the photo offline and replaced it with a cropped version that excludes her tummy.

When fans revealed that they were unconvinced, she later uploaded a photo of herself in a bikini showing off a very flat stomach.

The photo on the right is alleged to have been taken on a holiday last year as the singer is sporting a completely different hairstyle and has a visibly reduced bust.

The snap comes weeks after the 27-year-old songstress was seen leaving a fertility clinic with Diddy. If she is pregnant, it will be the first child for her and the sixth for the rap mogul.

This isn't the first time the couple have had to combat rumours about their relationship this year. In Feburary, Cassie took to Instagram to refute claims that she and Diddy were getting married.

P.Diddy aka Sean Combs is father to Justin (born 1993) from a relationship with designer Misa Hylton-Brim. Christian (born 1998) and twin daughters D'Lila and Jessie (born 2006) with Kim Porter, and daughter Chance with Sarah Chapman (born 2006).
