Blake Shelton and Gwen Stefani may prove to be a reality television couple that actually lasts. After Blake split from Miranda Lambert and Gwen dumped her cheating husband, Gavin Rossdale, the two judges on The Voice found love with each other. If they weren’t flirting at Halloween parties, they were Facetiming each other. They even commuted to work together! How sweet!

Though they had their problems in 2015, Kylie and Tyga were still one of the hottest celebrity couples of the year. Before they split in November, Kylie and Tyga were having “off the charts” sex. Kylie even bragged that Tyga was the world’s best kisser and she would return the favor by modeling sexy outfits for him in the bedroom.

Though they got back together shortly after their break-up, it almost seemed like things had cooled down. Not so — they reunited for a wild and intimate night out. What does 2016 hold in store for them?

Zayn Malik had a pair of painful splits in 2015. Not only did he break-up with his band, One Direction, he called off his engagement to Little Mix’s Perrie Edwards. However, the former 1D-hottie wouldn’t end the year a single man. He and model (and Taylor Swift bestie) Gigi Hadid began dating in November, shortly after Gigi herself broke up with Joe Jonas. Though fans were shocked at this new power couple, Zayn was completely in awe over his new girl.

Speaking of TayTay, she found love in 2015. She and Calvin Harris started dating, and her EDM hunk has been a perfect boyfriend for the “Wildest Dreams” singer. When they’re not sharing romantic PDA on hot dates, they’re getting sexy with racy lingerie for romantic nights at home. They even spent Taylor’s birthday and Christmas together, giving each other the gift of love. Awww!
