Liverpool model Abbey, who stormed to victory with Aljaz last year to be crowned the Strictly champion, was in a celebratory mood as she joined her fellow celebrities at the bash held at Velvet Hotel.
Abbey showed off her legs in a black minidress with sheer sleeves and clutched onto a glass of wine while arm-in-arm with Aljaz.
The duo were joined by the likes of Susanna Reid, Nicky Byrne and Mark Benton, who are also competing in the live tour.
Abbey arrived at the party with professional dancer Iveta Lukosiute - and both ladies wowed in their sexy minidresses.
The girls had earlier spent the day shopping in the city centre along with fellow dancer Natalie Lowe.
Posting a photo of the trio in a clothing boutique, mum-of-one Abbey, who is married to footballer Peter Crouch, said: "Having a great shopping trip with my girls @D8Iveta and @RealNatalieLowe xx."
The 'Strictly Come Dancing Live Tour 2014' kicked off on 17 January and will come to end on Sunday 9 February at London's O2 Arena.
The tour mirrors the hit BBC show where celebrities are pitted against each other on the dance floor to win the dance of the night.
