Coronation Street's Shobna Gulati and TV star John Barrowman have been named top of the bottoms.
The pair were victors in the Wizard Jeans Rear of the Year after winning a public vote for the cheeky title.
Gulati, who plays Corrie's Sunita Alahan, said she had to thank her mother for her prize-winning asset.
"I am really honoured and flattered to be a winner of this year's competition and for my bum to be etched into the history of the award's alumni - a list which includes so many other distinguished bottoms.
"And I'd also like to say thanks - in the words of Will.i.am, 'I got it from my mama'."
Barrowman is known for his role as Captain Jack Harkness in Torchwood and Doctor Who as well as his West End stage roles.
"With tush tightly toned, cheeks firmly clenched and a big smile on my face, I'm thrilled to be awarded the accolade," he said.
Previous winners of the title - now in its 30th year - have included Fiona Bruce, Gary Barlow and Rachel Stevens. Last year the awards went to Carol Vorderman and Anton Du Beke.
Sally Allen, of sponsor Wizard Jeans, called the winners "two excellent examples of this year's ideal rear".
"Shobna's slim but womanly silhouette is a fine example of the happy, healthy female form for 2012 and John's rear is clearly admired on an international basis, judging by the number of fans who voted for him. No doubt his dancing prowess helps to keep him in tremendous shape."
