Finding love in Hollywood is like looking for a needle in a haystack, with only a handful of celebrities finding the "one." On the other hand, several stars have been labeled serial daters, and apparently love the dating game.

While a celebrity like John Mayer has it all, he's known as one of Hollywood's top serial daters and can't seem to find a love that will last. Some of the most famous women he's been linked to include, Jessica Simpson, Jennifer Aniston, Taylor Swift, and Katy Perry, and as of 2021, he's still very much single and still on the prowl. Some of the celebs on this list may have given up their serial dating ways to finally settle down, but it's worth noting that it took them having to date several other celebs to finally find their partner.

10 Jennifer Aniston

Jennifer Aniston has had her fair share of ups and downs when it comes to finding love. Before she met and married Brad Pitt, the Friends star dated numerous men in Hollywood, including, Charlie Schlatter, Daniel McDonald, whom she called her "first love," Counting Crows frontman Adam Duritz, Tate Donovan, and Paul Rudd.

After her marriage to Pitt was shattered in 2005 because of cheating allegations, Aniston moved on and continued to casually date men like her The Break-Up co-star Vince Vaughn, John Mayer, Gerard Butler, and even got married and divorced again to Justin Theroux. Whew, that's one long list of exes.

9 George Clooney

George Clooney was believed to have given up on marriage after he got divorced from Talia Balsam in 1993. After his brief marriage, the actor went on to have long-term relationships with several women, including Celine Balitran, Lisa Snowden, Krista Allen, and Stacy Keibler.

However, Clooney is also known to have dated other A-list actresses for a brief period of time like Lucy Liu, Renee Zellweger, and Charlize Theron. Fans thought that Clooney would be a bachelor for the rest of his life until he met Amal Alamuddin, who he married in 2014 and has two children with.

8 Katy Perry

Katy Perry may have just welcomed her first child with Orlando Bloom in August 2020, but before she settled down with the actor, she dated quite a few men in Hollywood. The songstress was first linked to troubled actor Johnny Lewis back in 2005 and then began dating Gym Class Heroes lead singer Travie McCoy a year later.

Perry's relationships began to become more serious when she married comedian Russell Brand, but the two called it quits 14 months in. She has had an on and off relationship with John Mayer from 2012-2014 and has dated DJ and producer Diplo. Today, the star is happily engaged to Bloom.
