The Strictly Come Dancing winner, 28, took a break from rehearsing for the BBC1 show's official tour to unveil Marks and Spencer and Oxfam's latest Shwopping campaign, which is raising money for mums living in poverty around the world.
Abbey was joined by TV legend Joanna Lumley and presenter Zoe Ball at the event, and the trio were wearing matching navy blue 'Love, Mum' and 'Shwopping' jumpers.
Speaking about the campaign, Abbey - who has a two-year-old daughter called Sophia - said: "It's great that Oxfam is celebrating mothers around the world as mums really are amazing.
"Supporting the appeal is easy, you can donate unwanted goods to Oxfam shops, Shwop clothes in M&S, hold a fundraising event with friends, or simply donate money via Oxfam's website and you'll be helping mothers worldwide change their future."
It's been a busy few months for Abbey, who was crowned the winner of Strictly Come Dancing in December.
Along with the rehearsals for the 'Strictly Come Dancing UK Tour', Abbey was recently announced as the new face and body of underwear brand Ultimo.
