Following the ups and downs of lives of celebrity relationships is often like watching a real-life romantic comedy, or, in some cases, a romantic drama. From marriages going combust (Sandra Bullock and Jesse James) to new celeb couples (Blake Lively and Ryan Gosling), and from quick flings (Taylor Swift and Taylor Lautner) to enduring love stories (Ben Affleck and Jennifer Garner), there was no shortage of tabloid-worthy plot twists this year. And although there are so many celeb pairs to choose from, we’ve managed to chisel out who we think were the most fascinating couples of 2010:
1. Justin Timberlake and Jessica Biel: Sure, this couple has been dodging breakup rumors for over a year - Justin’s grandmother even said last year that "as far as we’re concerned, he’s always been single" - but they still seem to be going strong. Justin is know for his long, committed relationships—he dated Cameron Diaz for nearly four years, and supposedly Britney Spears for the same length—and seeing as he’s experienced his own heartbreak from infidelity (exhibit A: "Cry Me A River"), it seems somewhat unlikely that he would become a cheater himself. And Jessica’s certainly had her fair share of temptation - after all, she filmed Nailed with cutie Jake Gyllenhaal - but has never strayed. This couple’s commitment to each other is what makes them fascinating. They’ve been together since 2007, but who knows, maybe they’ll also fall victim to Justin’s four-year-relationship trend.

2. Kristen Stewart and Robert Pattinson: She’s the envy of nearly every teenage girl today, and probably even some adult women as well. He’s a lusted after English hearthrob. And although neither actor has officially confirmed they are exclusively dating, there’s been ample photographic evidence of their love. We hear that the next installment of Twilight will feature their characters Bella and Edward getting married, so perhaps wedding bells are not far off for the offscreen couple as well? If so, we would expect a super-private elopement, as the couple seems to value their privacy above everything else. Kristen Stewart: Robert Pattinson Is 'My Husband'
3. Chelsea Handler and 50 Cent: Their couple status may be un-officially confirmed, but that didn't stop Chelsea from be quite candid about her possible beau during a recent interview with Jay Leno. (The Tonight Show band also played Fifty’s "Candy Shop" during Chelsea’s entrance.) During the interview, Jay asked the comedienne how exactly to pronounce the rapper’s name ("Fifty or Fiddy?") and Chelsea responded, "I don’t know. I call him Curtis when we have sex." Apparently though, this was just a joke, as she later referred to him as a friend who hasn’t met her family yet. (She then joked that he couldn’t meet her family until he learned to swim.) We don't know what these two would see in each other, but, in any case, we'd love to see "Curtis" fix up Chelsea's BFF Jennifer Aniston with one of his rapper friends, so that they can double date in the new year.
