17 Bizarre Celebrity Couples From The 2000s That Time Forgot

And need to be remembered

The 2000s were definitely a pinnacle of celebrity couples. Many will always be memorable, such as Britney Spears and Justin Timberlake — those denim outfits belong in a museum — but other, less photogenic ones seem to have escaped to the back corners of the Internet's mind.

Whether the celebs were simply making out, had a brief fling, or were in a full-on relationship, these 17 couples's romantic histories deserve to be remembered for posterity.

Rihanna Shia LaBeouf

These two actually went out on a date in 2007, but it reportedly didn't end very well. LaBeouf told Playboy, "It never got beyond one date ... The spark wasn’t there. We weren’t passionate about each other in that way, so we remain friends."

John Mayer and Jessica Simpson

John Mayer Jessica Simpson

They famously dated from 2006 to 2007, with Mayer describing Simpson as "crack cocaine." In a tell-all interview with Playboy, Mayer said their relationship was like "sexual napalm." They were also parodied on Saturday Night Live, which is the easiest way to tell if your relationship is weird to others or not.

Simon Cowell and Carmen Electra

Simon Cowell Carmen Electra

How does a persnickety British music judge end up dating a former Baywatch star? Well, according to Electra, it never happened, not in the ~true~ dating sense. After being flirty texters, Electra apparently made out with Cowell at his party, which is how the paparazzi "uncovered" their relationship. Still, Electra maintains: "We never dated. We didn’t date ... He wasn’t my man." But since they did kiss (probably), we're keeping them on this list.

Natalie Portman and Moby

The two briefly dated in 2001, and Moby told Spin that his relationship with Portman made him "the target of a lot of nerd wrath," which makes sense, actually.

Marilyn Manson and Evan Rachel Wood

The two started dating in 2006 — when she was 19 and he was 36. They were engaged in 2010, but eventually broke up. "I just don’t think we were right for each other," Wood said of Manson in 2015.

These two reportedly started dating in 2009, and MTV News made a handy timeline of their flirtation. After much speculation about whether they did or did not date, Handler set the record straight: "We dated, very casually."

Yep, Christian Grey and Anna Karenina dated from 2003 to 2005. Apparently, Knightley is the one who helped Dornan's acting career, introducing him to her agent. When they broke up, he apparently even wrote a song about his feelings.

Duff and Madden dated from 2004 to 2006; when they first got together, she was 16 and he was 25. The details of their romance are a bit, um, controversial, as Duff told Cosmopolitan: "I had a 26-year-old boyfriend. So everyone can make their own assumptions about what I was doing."

Britney Spears and Colin Farrell

Before Gosling dated his The Notebook costar, Rachel McAdams, he was with Bullock. They started dating after working on their film Murder by Numbers and were together from 2002 to 2003. Gosling spoke about Bullock and McAdams to The Times, saying, "I had two of the greatest girlfriend of all time. I haven’t met anybody who could top them."

Tom Cruise and Sofia Vergara

Tom Cruise and Sofia Vergara

According to a New York Post article — which has since been deleted — Cruise allegedly asked Scientology leaders to set him up with someone from his list of women he'd like to date. Business Insider summarized the article, which explained how Cruise wooed Vergara with flowers and chocolate at Will Smith's pre-Oscar party. Later on, Cruise's pal (and Scientology leader) David Miscavige apparently tried to prep Vergara to be Cruise's wife, which would mean renouncing her Catholic faith and adopting Scientology in its place. The whole ordeal sounds super sketchy, TBH.
