Sam Claflin and Laura Haddock are expecting their second child

Huge congratulations are in order for Sam Claflin and Laura Haddock, as the couple are expecting their second child.

Laura, who shot to fame after playing Alison in The Inbetweeners Movie, was spotted with a growing baby bump as she attended a jewellery launch this week.

The 32-year-old was in a pretty pastel pink dress as she cradled her stomach in photos.

Laura also shared a snap on her Instagram to her 124k followers, prompting lots of congratulatory messages, as well as a few making guesses at the gender of the baby...

One asked: 'Congrats! It's a babygirl?👭', while another subtly hinted with a pink bow emoji: 'Hope all is well during your pregnancy 🎀'.

'Congratulations - seems like your family is going to get a new little member!' a third exclaimed, while another added: 'So happy for you laura!!! congratulations!'

'Beautiful dress and beautiful baby bump! Congratulations!' another excitedly wrote.

Laura and actor husband Sam, 31, who found fame in movies The Hunger Games and Pirates of the Caribbean, are already proud parents to son, Pip, who turns two in December.

The pair are private abut family life and didn't share their first born's gender until six months after the birth.

Talking to PEOPLE magazine about being a dad, Sam said: 'You can't describe to someone unless [they're] in it... The rewards are just endless. He's literally the best thing that's ever happened to me.'

The couple, who started dating in 2011, married in a private ceremony in July 2013. The actor said that it was love at first sight when he met Laura at an audition.

'We met at an audition for My Week with Marilyn and there was an instant spark,' he said at the time. 'We found out we had the same agent and then bumped into each other the next morning at [a London Underground] station.

'I didn't know anything about her other than that her name was Laura, she was very attractive and she seemed lovely.'
