18 Celebrity Hookups That Took The World By Surprise

…who just happens to be the son of former California governor (and Terminator) Arnold. The two were spotted making out at a USC football game in fall of 2014. (Is it just me, or should Schwarzenegger pay a liiiiittle more attention to Cyrus and less to his phone in this photo?)

The Spring Breakers actress was recently spotted out with this DJ.

Gomez and Zedd recently shared Instagram pics featuring the other, including one of Gomez lounging in bed. An odd match, but, hey, at least she’s trying to get over Justin Bieber.

No one saw this alleged hookup coming.

Rumor has it that the Wolf of Wall Street actor and the “S&M” singer had quite a few “midnight hookups” in January of 2015.

Jaws dropped when fans learned that the Wolfman actor had a quick fling with this socialite…

…probably because it led to a daughter! Stewart and Del Toro had a brief relationship in 2010, which was kept mostly under the radar. In 2011, Stewart gave birth to their child, Delilah.

Tabloids looooved to talk about the alleged hookup between these two celebrities — probably because they’d make an impossibly gorgeous couple!

Okay, okay… so this probably didn’t REALLY happen. But what is so random is that everyone thought that it did. The two were allegedly seen “canoodling” at an event, which led to tabloids speculating that they were, in fact, macking. Swift fired back on Twitter about how ridiculous the whole thing was. Can’t two semi-identical celebs hang out without everyone suspecting it's more than that?

The That Awkward Moment actor was spotted out with this Fast & Furious actress.

Rodriguez and Efron were hot and heavy for a few weeks back in the summer of 2014, and were even spotted hooking up at a club in Ibiza. Unfortunately, the fling didn’t last.

One fling that did last? The love between these two unexpected vampires.

The Twilight actress and the Vampire Diaries star got together not long after both split with their significant others. (Reed was actually pals with Somerhalder’s ex, Nina Dobrev!) They’re still together, and rumor has it that they might be walking down the aisle in the future…

The rapper didn’t waste any time getting with this pop star after his relationship with Naya Rivera fell apart.

Grande confirmed her relationship with the “IDFWU” rapper to Telegraph Magazine in October of 2014, even calling him one of the most “amazing men” in the world. The two are pretty hot and heavy, especially considering both got out of serious relationships — him with Glee actress Naya Rivera, and her with Jai Brooks.

Eyebrows were raised when this Glee actress started dating her current beau.

One year after the death of her boyfriend Cory Monteith, Michele began dating Paetz — whom the press quickly found out used to be an online gigolo. Sure, it’s not exactly the easiest info to swallow, but these two are still together and seem crazy happy — which really is the most important thing.

The former American Idol judge had a brief relationship with this celebrity.

Electra went on a few dinner dates with Cowell and stated that he’s “very charming” — but it wasn’t enough for the fling to become the real deal.

Rumor has it that the “West Coast” singer has a thing for pale dudes.

The shock rocker allegedly had a one-night thing with Del Rey while the two were hanging out together in Berlin. Imagine the musical possibilities…

The Desperate Housewives star went on a few dates with this host.

Back in 2006, Seacrest took Hatcher out on three occasions before deciding to end things with the TV star. The really bad news? It was right after their very first kiss.

The Oscar winner was spotted getting cozy with this former Full House actress.

Leto was allegedly seen canoodling with one-half of the Olsen twins in May of 2014. Kind of random, sure — but am I the only one who thinks that this pair could totally be a thing?!

Apparently this guy has a thing for pop stars.

From Katy Perry to a Spice Girl! The two Brits allegedly hooked up not long after Brand’s divorce from his wife, but things didn’t last.

Things got reallll scandalous when the Snow White and the Huntsman actress was seen smooching her married director.

Paparazzi caught Sanders and Stewart making out, which shocked fans — but probably not as much as it shocked their significant others. Sanders was married to former model Liberty Ross and Stewart was attached to her Twilight co-star Robert Pattinson.

The Game of Thrones beauty used to date this comedian.

Yep, Stewie Griffin used to date Daenerys Targaryen! The two were an item back in 2013 but things eventually fizzled out.

The socialite (turned DJ, just in case you forgot) was spotted hooking up with this action star — and there are plenty of pics to prove it.

Kilmer and Hilton’s tryst was exposed in an Australian magazine. The tabloid ran photos of the two celebrities getting hot and heavy, despite the fact that the Top Gun actor once criticized the socialite for being “famous for nothing.”

The model/actress raised eyebrows way less fierce than hers when she hooked up with this celeb.

Looks like her tryst with Zac Efron wasn’t the only surprising hookup Rodriguez had in 2014! She also got together with Delevingne for a quick romance early in the year. The two were spotted kissing at a basketball game.
