Celeste Barber has made a return to social media following the shock news she has separated from her husband Api Robin.

The 43-year-old comedian shared a gallery of video clips to Instagram on Wednesday, in which she cheerfully promoted her BOOIE Beauty label's new sunglasses.

She beamed as she modelled the slick eyewear in a variety of different poses, excitedly telling followers that they are set to be launched on Thursday.

She also appeared in a cheeky ad for the label, in which she arrives on set to film a commercial and then has to leave as she had forgotten to bring the sunglasses.

'A collab that felt inevitable, and feels just right. ⁠BOOIE's always been about getting you out the door, feeling good, without overthinking it. ⁠Lips on. BAM⁠. Cheeks done. BAM⁠. Sunnies on. BANG⁠,' Booie wrote on social media.

Celeste made no mention of her husband in the posts, which comes a week after he announced their shock split. 

Api confirmed the couple had decided to end their marriage after 20 years together a day before Valentine's Day. 

'The past few months have been incredibly challenging and deeply heartbreaking for us both,' an Instagram post, captioned 'Heavy hearts', began.

'After much reflection, the decision has been made to separate.

'There is still love and respect between us, but sadly we are at capacity and have come to recognise we may want for different things.

'Our priority remains our children and their wellbeing. We kindly ask for privacy and understanding as we navigate this.' 

While most were blindsided by the breakdown of their seemingly strong marriage, a glance at their online footprint and previous interviews reveal there have been signs of trouble in paradise for years. 

Most recently, their social media posts have been entirely absent of one another, with both Api and Celeste sharing their last photo together in early November.

Celeste had just wrapped the US leg of her Backup Dancer tour with Api tagging along for the ride, sharing loved-up posts about their trip together. 

She kicked off the tour in late October, with footage showing Api joining her backstage and expressing his pride over her blossoming career. 

But their final post together came in the first days of November when the US tour came to an end and the couple jetted back home to Australia. 

Celeste shared a reel of photos and videos from the trip on November 1, showing the pair looking happier than ever as they attended events and cuddled on a train.

The following day, Api shared a similar post that appeared to be even more loved-up as he said he was 'so proud' of his wife. 

Since then, neither have mentioned each other on their social media accounts, with Api even changing his bio from 'hot husband' to 'formerly hot husband'.

Christmas and New Year came and went without the pair sharing their usual heart-warming celebrations and tributes to one another - an unusual move given how frequently they share their married lives online.

It seemed Valentine's Day would be the telling moment, with eagle-eyed followers holding their breath to see if Celeste and Api would reaffirm their love for each other.

However, Api swooped in at the last minute, beating Saint Valentine to the punch as he revealed on February 13 he and Celeste had split.

The couple share two sons named Lou Robin and Buddy Robin, while Robin has two daughters from a previous marriage.
