Gwen Stefani and Blake Shelton
While some celebrity couples keep mum about their relationships, these two love to dote over each other on social media and in public -- and they're very good at it. Case in point: Upon being honored at Glamour's Women of the Year Awards in November, Stefani praised Shelton for his support over the past year. "I am so honored and grateful. And to my children, to my family, to Blake Shelton for kissing me back to life, thank you so much. I am blown away!" she exclaimed. The "Misery" singer also told ET at the event, "It's incredible to have a best friend like that guy. He's an amazing person." And their red carpet debut at the GRAMMYs in February? Hubba hubba!
Chrissy Teigen and John Legend
Jennifer Aniston and Justin Theroux
Katy Perry and Orlando Bloom
And PDA? We saw that, too. In fact, Bloom was quite uninhibited during a beach vacation with his pop star girlfriend in August. While his naked paddle boarding made the most headlines, Bloom also got pretty handsy with Perry while frolicking in the sun and surf -- not a first for them that summer.
Blake Lively and Ryan Reynolds
David and Victoria Beckham
And the honeymoon certainly isn't over for these two -- during a rare joint appearance at the Global Shopping Festival Countdown Gala in China, Victoria shared a Snapchat story of herself gawking at her husband's toned butt. Can you blame her?
Keith Urban and Nicole Kidman
In the actress' follow-up appearance, Fallon was visibly surprised when Urban showed up onstage and planted a big kiss on his wife’s lips. Kidman then sat on her husband's lap. "How did you pull this off? How did I not see you?" the shocked host exclaimed. "I even visited you quickly backstage to say hi, and you didn't bring this up at all."
Jessica Biel and Justin Timberlake
The "Can't Stop the Feeling" singer shared a super cute photo of Biel holding their son Silas on Mother's Day that was accompanied by an equally adorable caption. "M.I.L.F. Alert!!!! Happy Mother's Day to this AMAZING MOM AND WIFE," Timberlake gushed. "And, to all of the mothers out there... You keep the world turning!! Hope every single one of you has an amazing day!" Not only that, but the duo packed on rare PDA at the Critics' Choice Awards in December.
Chris Pratt and Anna Faris
Tom Hanks and Rita Wilson
In October, ET celebrated Wilson's 60th birthday with the couple at the L.A. premiere of Hanks' film, Inferno. Doting on his wife, Hanks shared the best advice he ever received from his spouse: "Go change... change that! Get out of that! Go back in your closet, you're not wearing that tonight! I used to have this thing that -- I loved it -- was a baseball jersey from Japan. It was great! It had pin stripes, it was old and it said Nerima, which is I guess a neighborhood in Tokyo. And she actually started warning me in advance, 'This is a non-Nerima event we are going to tonight.' It used to make me mad but now I've come to accept it."
Sarah Paulson and Holland Taylor
Ciara and Russell Wilson
Channing Tatum and Jenna Dewan-Tatum
Tatum was just as kind while speaking of his wife. When Dewan-Tatum turned 36 in December, her hubby penned her a loving birthday message on Instagram: "@jennaldewan I'm not sure if this woman is my Rainbow or my pot of gold but I'm lucky either way happy birthday cake baby!"
Prince Harry and Meghan Markle
An American in Buckingham Palace? It's possible now that Harry is dating Markle. Not only was the royal twinning with the Suits star when the first pic of the pair together was snapped in London in mid-December, the chivalrous prince went public about his relationship by defending Markle against disparaging comments and invasion of privacy in a lengthy statement released by the Kensington Palace on his behalf.
"It is not right that a few months into a relationship with him that Ms. Markle should be subjected to such a storm," the statement read. "He knows commentators will say this is 'the price she has to pay' and that 'this is all part of the game.' He strongly disagrees. This is not a game -- it is her life and his." Points, Harry!
