Former X Factor contestant Rebecca posed for a photograph backstage while wearing a dazzling sequinned dress and turned to the side to show off her tummy.
Rebecca was performing at the Henley Festival in Berkshire last night (13 July) and looked super-glam, wearing her hair in long soft waves and vamping up her look with a red lippie.
Alongside a close-up selfie, which gave us a good look at her enviable make-up, Rebecca simply said: "Showtime Henley."
In April, Rebecca confirmed that she was pregnant with her third child, adding that she feels "grateful" to be expecting again. The star has, however, kept the father's name a secret.
Last month, Rebecca shared a scan picture and told fans she is having a girl called Arabella, although she sparked concern with her cryptic Instagram caption.
Rebecca said: "You wasn't expected you wasn't planned [sic] but I'm thankful that I was chosen to bring you into this world.
"Feel a special bond because when everybody said you was wrong I fought for you, i held my ground and said every child has a right to live.
"Feel like god blessed me with someone who I know will always bring me joy my princess my precious unborn Arabella xxxx."
Thankfully, Rebecca now seems to be in brighter spirits and last week tweeted: "#quoteoftheday I don't know why I'm here on earth but I know what makes me happy so I will keep doing what makes me happy LOVING PEOPLE!"
