Jessica Biel sent fans into a spin as she shared a very rare family photo with husband Justin Timberlake.

The Sinner actress, 39, and SexyBack singer, 40, are notoriously private about their two sons, Silas, 6, and Phineas, 17 months.

In fact, they are so low-key that they didn’t even officially confirm their second child’s arrival until six months after his birth.

Taking to Instagram, the mum-of-two commemorated Christmas with two photos as she strolled along with her husband and their brood.

In the upload, she could be seen holding Phineas in her arms on the family walk, sandwiched between her eldest son on one side, and her beau on the other.

‘Thankful for my guys…,’ she simply captioned the upload. ‘Merry Christmas everybody!!’

Right on cue, fans flooded the comments section with praise for the rare snap – as well as their decision not to share their sons’ faces online.

‘Sooo stinking cute also #privacy,’ a follower replied.

‘Not everyone wants their Childrens faces on the internet. Beautiful family and moments spent together!…Thanks for sharing,’ another agreed.

An Instagram user said: ‘So normal and beautiful!!!’

‘Beautiful family Merry Christmas guys,’ one commented

‘Merry Christmas and Happy New Year,’ a fan added. ‘They grow up in an instant. Enjoy the ride, it’s a beautiful stage of life.’

Jessica and Justin welcomed their second child together last summer but managed to keep the whole thing under wraps, with no public confirmation or photos of the A Team actress’ baby bump making the rounds.

However, she has insisted that she never intended for it to be a secret pregnancy – it just happened to coincide with the global pandemic.

Speaking of her baby news during a recent appearance on the Armchair Expert podcast, she told host Dax Shepard: ‘I had, like, a secret Covid baby. It wasn’t like it was supposed to be a secret. 

‘It was just Covid happened, and then I went to Montana with my family and never left.’

Jessica also spoke of the little one’s birth, sharing how grateful she was that by the time she went into labor, hospital restrictions had eased slightly, meaning Justin was able to be by her side.

‘There was a moment there that there was nobody allowed at all and I was really getting nervous about that situation,’ she added.

‘But yes, he was allowed. I think if I had to be there alone, that would have been horrible. I would have been really scared.’
