Justin took to Instagram to announce his exciting news on his birthday

Kissing his wife Jessica Biel‘s naked baby bump in the snow, this is Justin Timberlake‘s adorable way of confirming he’s about to become a dad.

Justin, who turned 34 yesterday, celebrated his exciting news by posting this picture on his Instagram account. Thanking everyone for wishing him a happy birthday, the dad-to-be was clearly bursting with pride as he wrote in the caption:

‘Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets

Hollywood has been awash with speculation that the singer is expecting his first child, after pictures emerged of his actress wife Jessica with what appeared to be a small baby bump.

The notoriously private couple, who began dating eight years ago, married in an intimate ceremony in Italy in October 2012.

Jessica, 32, has always said her and Justin would like to have kids ‘at some point’. Justin, who counts Britney Spears and Cameron Diaz as exes, has always chosen not to talk too much about Jessica but revealed in an interview in Vanity Fair in 2011 that his relationship with her is the most special he has ever had.

He said: ‘She is the single-handedly most significant person in my life. In my 30 years, she is the most special person.’

And in 2013 he told Ellen DeGeneres how happy he was to be married to her.

‘Every once in a while I can catch a glimpse of her when she doesn’t see me looking, and I have this moment where I’m like “If you only make bad decisions for the rest of your life, you made one really good decision”,’ he said. ‘It’s nice to marry your best friend. It suits me.’

Their baby will certainly have lots of adoring celebrity fans. Taylor Swift, Beyonce and Jay-Z are all close friends to the couple.
