Ellie Warner is believed to be concerned over "what the future might hold" following her boyfriend Nat's horror brain injury.
The Gogglebox star, 31, is currently receiving help and support from brain injury charity Headway, which helps survivors and their families.
While Ellie is yet to speak about Nat's injuries - which he sustained on March 18 following an accident - she broke her silence on social media to ask for donations to the charity in lieu of gifts for her birthday.
Nat had initially been placed on life support after the crash and was believed to be in critical condition.
A family member later said that he had suffered two collapsed lungs and a broken neck.
Deputy Chief Executive of Headway, Luke Griggs, told The Sun : "The thoughts of everyone at Headway are with Nat and Ellie, as well as their family and friends.
“We understand the pain and anguish of sitting by the hospital bedside of a loved one following a brain injury. Often the concern around their current condition is compounded by uncertainty over what the future may hold."
He added that they were "extremely grateful" that Ellie was supporting the charity and that the "immediate aftermath of a brain injury can be daunting".
On Wednesday evening, Ellie wrote on her Facebook page: "For my birthday this year, I'm asking for donations to Headway - the brain injury association. I've chosen this charity because their mission means a lot to me, and I hope that you'll consider contributing as a way of celebrating with me.
"Every little bit will help me reach my goal. I've included information about Headway - the brain injury association below.
"Headway's mission is to promote the understanding of all aspects of brain injury and to provide vital information, support and services to people with a brain injury, their families and carers."
She has already raised £1,315 which far exceeded the £150 target she set up and also posted a link to the charity.
It is believed that Ellie, who appears on the TV-watching programme alongside sister Izzi, will continue to be paid her £1,500 show fee.
