Congratulations are in order for Jessica Alba and Cash Warren

'We're going to be outnumbered'

2017 is definitely the year of celebrity babies with A-listers announcing their pregnancies and Instagramming their newborns left, right and centre.

The past few months have seen both Amal and George Clooney and Beyoncé and Jay-Z welcome twins, whilst other celebrities that became parents range from Rosie Huntington-Whiteley, Zooey Deschanel and Gal Gadot, to Bradley Cooper, Irina Shayk and Natalie Portman.

However the latest celebrity to announce a baby bump is 36-year-old actress Jessica Alba, who took to social media to share the news that she was expecting a baby.

Jessica and her film producer husband Cash Warren already have two daughters: nine-year-old Honor and five-year-old Haven - both of whom featured in Jessica's sweet pregnancy announcement.

Taking to Instagram, Jessica shared a sweet video of the three of them, with Honor and Haven holding large balloons shaped like the numbers one and two, with Jessica holding a balloon in the shape of a number three over her growing baby bump.

She captioned the video: 'Cash Warren and I are officially going to be outnumbered #babyonboard #herewegoagain ????#blessed?'

The actress has previously spoken out about the struggles of motherhood, opening up to Yahoo Parenting about the harsh expectations and pressure that comes with it.

'I know as a mom — and as a new parent — I felt confused. And I felt judged,' she explained. 'I think the biggest thing is that what works for you, or what works for your friend, isn't going to work for everyone … there is no right or wrong. There’s no cookie-cutter way of going about it. And I think we as women — and as moms — we need to show younger girls that we support each other no matter what. And to try and not be so judgemental.'
