Rochelle Humes gets ''stuck'' in her pregnancy pillow.

The Saturdays star - who is expecting her first child with her husband, JLS singer Marvin Humes - has been using the special maternity pillow to help her find comfort after having trouble sleeping, but is worried that she can't get out of it.

She wrote on Twitter: ''No matter how tired I am im finding it so hard to sleep ... I feel like a have a football team in my stomach.. (sic)

''I did get a pregnancy pillow which helps a bit but I feel like I'm stuck in it. Haha I cant roll over ... anyone else? (sic)''

The 'What About Us' singer was thrilled to learn she isn't the only expectant mother experiencing the problem, however.

After receiving responses from fellow mums-to-be, she added: ''Lol glad it's not just me.. :-) (sic)''

Rochelle - who is currently starring on E! reality show, 'Chasing The Saturdays' about the band's attempts to crack America - recently admitted she struggled to hide her pregnancy from bandmates Una Healy, Mollie King, Frankie Sandford and Vanessa White.

The 23-year-old beauty said: ''Being pregnant is the hardest secret to keep anyway because you have to wait for the safe point it was definitely strange. The girls were saying, 'Let's go out for sushi,' and I'm the biggest leader for that usually. I'd go quiet and disappear into my room.

''They all had 'the chat' without me and said, 'Are you pregnant?' ''
