Will these new celebrity couples be ringing in 2016 together?
The loved-up pair has been dating since November, shortly after Gigi's split with singer Joe Jonas, and just three months after Zayn reportedly ditched Little Mix singer and fiancee Perrie Edwards (22) by text.
They were first spotted together following Justin Bieber's AMA after party and Zayn reportedly fell for the model when he watched her stroll down the catwalk at the Victoria's Secret Fashion Show in November.
They've since shared their first Instagram selfie as a couple and apparently bond over their love of family and "drinking beer".
The 30-year-old TV presenter has been dating Sunset Sons frontman since July. After a three year on/off relationship with Danny O’Reilly of The Coronas, it looks like the Bray girl is very much on with new rocker beau.
The pair even made it ‘Instagram official’ in August and Rory jetted out to Australia to spend time with Laura when she was on presenting duties for I'm A Celeb.
Both were newly single when they first met in April – Bradley split with model Suki Waterhouse and Irina from footballer Cristiano Ronaldo.
They've since been photographed getting steamy on a beach in the Bahamas, as well as enjoying multiple dinner dates together. Things are moving so quickly we expect to see the Russian supermodel at the Oscars.
Sarah Paulson and Holland Taylor
The 19-year-old model and sister of Gigi Hadid has been dating Canadian musician The Weeknd (real name Abel Tesfaye) since spring.
The dark-haired beauty also appeared in The Weeknd's gritty new music video and is said to be "in awe" of her boyfriend.
The former Miss Ireland and Herald columnist (24) has been dating The Coronas frontman for the past few months.
Danny (29), who previously dated top TV presenter Laura Whitmore, is notoriously private about his personal life and has kept quiet about the relationship.
However, a source said that it's "still early days" between the pair but that things are going well between him and Holly, whose ex is Ireland rugby star Cian Healy.
Jennifer Lawrence and Hunger Games co-star (and long-rumoured love interest) Liam Hemsworth reportedly packed on the PDA at a dinner in New York last month, sparking rumours that they're officially a couple.
Romance rumours have long followed J-Law and L-Hem during their recent press tours, whenever they have both been single.
"Everyone knows what's going on, the chemistry is so obvious," an insider said to Heat magazine.
"They're so compatible, and it's not just about looking good together. They have the same sense of humour - when they're together, they laugh non-stop."
Activist and supermodel (of course) Kelly is said to be the woman who finally tamed one of Hollywood’s most eligible bachelors. The couple are reportedly engaged since September, but have yet to confirm the reports.
Either way, we’re devastated.
Hasn't the Mullingar man done well for himself? Niall (22) was spotted kissing Selena Gomez (23) at actress Jenna Dewan Tatum's birthday party in November. The brunette beauty was also seen backstage at the UK X Factor final when One Direction performed on stage.
In a game of "sleep with, marry or cruise" with James Corden, Niall revealed he'd "marry Selena Gomez".
Selena seems to be just as smitten as earlier in the month she tweeted a picture of Niall Horan's hometown friends, along with the caption "I have a serious thing for Mullingar guys" - she later joked she didn't caption the image, hinting it was Niall's friends... but sure if the mates are joking around with her already, it has to be serious.
The superstar singer has been dating the Australian business mogul since the summer. The billionaire is the first man whom Mariah has been romantically linked to since her separation from husband of eight-years Nick Cannon in 2014.
She previously admitted her first Christmas after the break-up was tough for her and the kids but James joined Mariah and her children for the holidays in Aspen, Colorado before heading to Melbourne, Australia ahead of the award-winning singer's planned New Year's Eve performance in the city.
We're familiar with the perils of high-profile celebrity coupling in an industry where relationships come and go. That's why it's refreshing to see a Hollywood star fall in love with a partner who isn’t in the spotlight; someone with a ‘normal’ life and a ‘regular’ job.
