Jaime Winstone is ''convinced'' she's having a son.

The 'Made in Dagenham' actress is five months pregnant with her first child and although she hasn't found out the sex of the baby, she's certain it will be male because her boyfriend James Suckling's family ''are all boys''.

Speaking at the WXXX event in London to celebrate the launch of W Amsterdam, she said: ''James' family are all boys and I've suffered with morning sickness which is meant to be a sign, I'm convinced it's a little boy in there!''

The 30-year-old star - whose father is acclaimed actor Ray Winstone - only started dating the DJ in March but revealed she was pregnant with an Instagram update last month which featured her TV presenter pal Miquita Oliver who had her hand placed on the star's bump.

Alongside the snap, she wrote: ''Me and @james_suckling are very pleased that we are having a baby!! So Magic, I'm going to be a mama xxxxx here is auntie @miquitaoliver having a cuddle xxx (sic)''

Although the tot will be Jaime's first baby, James already has young sons Ruffus and Hudson with his former girlfriend Lucy Brice.

Other guests at the WXXX event included Sadie Frost, Millie Mackintosh, Zara Martin and Diana Vickers.
