Rochelle Humes thinks her baby will be tall.

The Saturdays singer is nervous about giving birth to her first child with her JLS husband Marvin Humes and thinks their child will tower above his peers because the couple don't struggle for height.

Speaking on British TV show 'Daybreak', Rochelle said, ''I'm about eight weeks away'', adding, ''The poor thing will be quite lanky I think - we're the tallies!''

However, her bandmate Frankie Sandford was more complimentary and gushed: ''It's going to have the most perfect skin.''

The couple - who recently revealed they conceived their baby during a romantic break in New York - are set to become parents in May, and heavily pregnant Rochelle has thoroughly enjoyed the last few months of her pregnancy.

The 23-year-old star joked her fellow girl band members - Frankie, Una Healy, Mollie King and Vanessa White - are being extra nice to her and giving her special treatment.

Rochelle said: ''I always get the seat, which is great.''

The girls also discussed the smash success of their fly-on-the-wall reality show 'Chasing The Saturdays', claiming it feels ''mad'' they are now recognised internationally.

Mollie explained: ''It's good because people do get to know us as individuals then as well. For the American market - they get to know us as a band and as individuals. Over here [in the UK], people know us already as The Saturdays.''
