He had a devastating start to the year, when he and his wife Leah lost their two-year-old Henry in January this year, following a battle with cancer.
And Rob Delaney made a return to the London social circuit on Monday afternoon, when he attended the BAFTA Craft Awards, held at The Brewery.
The 41-year-old Catastrophe star – who paid tribute to ‘sweet little boy’ Henry on what would have been his third birthday last week – looked upbeat and relaxed as he stepped out for the ceremony in dapper style.
Looking sharp in a classic black tuxedo, which he teamed with a crisp white shirt and polished black leather shoes, the screen star highlighted his famous good looks with a perfectly coiffed comb-over, complementing his greying stubble.
Accompanied by a female pal, he was seen laughed and chatting as he mingled with a host of well-heeled guests at the exclusive event.
His outing comes days after he shared a moving photograph of Henry, taken shortly before he died, to mark what would have been his third birthday last Monday.
Henry had surgery to remove a brain tumour following his diagnosis in 2016, but the cancer returned in the autumn of 2017, and his devastated father confirmed his death in a Facebook post in February, telling fans he would ‘endeavour to not go mad with grief’.
Rob, who was born in the US but is based in London, posted a snap of the little boy leaning on a statue of a turtle clutching a toy bus, apparently taken on a family day out.
Rob, who has two older sons, aged six and five, with his wife said of the photograph: ‘You can see his little tracheotomy tube on his neck and his left eye is turned in due to nerve damage from surgery. He has a bus & a turtle though so he’s happy.’
Rob, who has over 1.5million Twitter followers, was inundated with messages of support from fans after sharing the post, which has been liked more than 10,000 times.
His moved fans praised him for talking openly about his family’s loss, and for his efforts to drum up support for both the NHS workers and the charities that had been there in Henry’s hour of need.
‘Thank you for sharing your family’s and your son’s journey with us, and for all you do to help other children and families in need,’ one follower said.
Another wrote: ‘I can’t imagine in a million years what you guys went through. Love and respect.’
Others told the star they admired his ‘openness’ around such a painful subject.

Delaney explained in his Facebook post that while brain surgery had left his son with ‘significant physical disabilities’, the toddler found his own ways to overcome his challenges.
‘He quickly learned sign language and developed his own method of getting from A to B shuffling on his beautiful little bum,’ Rob wrote at the time. ‘His drive to live and to love and to connect was profound.’
Delaney also paid tribute to the NHS staff who cared for his son, saying Henry’s doctors and nurses would be ‘my heroes until the day I die’.
He also praised the support the family had received from the charities Rainbow Trust, and Noah’s Ark Children’s Hospice.
