Celebrity Romances 2015
Jennifer Aniston and Justin Theroux(01 of15)
A long engagement meant it had to happen one day, but they still pulled off a backyard ceremony without the world's press posing as waiters. Surprise factor: 2/10
Taylor Swift and Calvin Harris(02 of15)
This is the music equivalent of a power marriage - each of these two at the peak of their respective careers, both with startlingly impressive makeovers in the last couple of years, and both beautifully tall. Surprise factor: 1/10 (the one being for why it took so long!)
Jamie Bell and Kate Mara(03 of15)
A cool indie coupling, tipped into paparazzi-ville by their co-starring in 'The Fabulous Four'. Surprise factor: 0/10
Elizabeth Olsen with Tom Hiddleston(04 of15)
Cara Delevingne and St Vincent(05 of15)
NOTHING Cara does would surprise us, but an uber-chic girlfriend does nothing to dent her appeal. Surprise factor: 3/10
Rupert Murdoch and Jerry Hall(06 of15)
When it was first rumoured, we just wished it could be true. And now it seems to be, with the former Mrs Jagger recently playing host to family drinks for the Murdoch clan. If walls had ears... Surprise factor: 10/10 - you had us.
Kylie Minogue and Joshua Sasse(07 of15)
If we didn't get the message with the appearance of Joshua in Kylie's Christmas video, with his delivery of flowers on stage at the Royal Albert Hall, we got it when he appeared on DESERT ISLAND DISCS to recite a surprise poem for his lady. And Kylie cried. The lady's a goner. Can we expect wedding bells in 2016?Surprise factor: 5/10 - with 4 points for Kylie's PDAs.
Alexander Skarsgard and Alexua Chung(08 of15)
A meeting of beautiful minds... Surprise factor: 0/10
Ferne McCann and George Shelley during 'I'm A Celebrity'(09 of15)
Wa it ever real? Surprise factor: Can we do negative numbers?
Blake Shelton and Gwen Stefani(10 of15)
Revenge on their errant exes is a dish best tasted with your 'Voice' co-judge. Nobody can fail to be happy for this pair. Surprise factor: 6/10 - seems a bit soon, but who cares??
Serena Williams and Drake(11 of15)
A new face at ladies' tennis matches is Drake, there to support the reported champion in his life Serena. Surprise factor: 6/10 - that's a lot of tennis he has to sit through.
Bradley Cooper and Irina Shayk(12 of15)
In another round of music chairs, Bradley's moved on from Suki Waterhouse to fellow model Irina, while the Russian stunner has traded in Ronaldo for a fellow high achiever. Whatevs. Surprise factor: Shrug.
Katie Holmes and Jamie Foxx(13 of15)
Never confirmed, but rumoured for over a year that Tom Cruise's ex-wife is making music with his 'Collateral' co-star Jamie. We hope it's true just for the disparity between these two. Surprise factor: 7/10
Louis Tomlinson and Briana Jungwirth(14 of15)
Parenthood, 21st-century pop star style. A million One Direction fans' hearts were broken by Louis' announcement he was about to become a baby-daddy, even if he hasn't proved quite the settling-down type. Surprise factor: 8/10
Zayn Malik with Gigi Hadid(15 of15)
More beautiful people taking photos of each other, which is how we know it's real... Surprise factor: 7/10 (because the last he told us, Zayn was hoping to lead "a normal life")
