She and a friend moved to Las Vegas in 2002, shortly after graduating high school. She began her career in the adult industry as a stripper at Palomino's in 2004. It was there that she became friends with another dancer who was also an escort and had appeared in a few adult films. After expressing interest, her friend put her in contact with adult talent agent Tomas of the agency Skin City Models. In 2004 Kelly shot her first hardcore sex scene and has since been featured in over 250 adult films; numerous box covers; and posed for several pictorials and layouts, both online and in print.

She often uses the alias stage name Kelly Fuckin' Wells, and has described her reasoning in an interview with AdultFYI as such: It's kind of like the girl next door with a kick. You know what I mean? Kelly has been nominated for a few adult industry awards during her short career, including AVN's Best New Starlet (2006) and XRCO's Super Slut and Orgasmic Analist (both 2005).

She is one of the few female adult film stars to have done DAP (Double Anal Penetration) and has now centered her career on this. She has also done DPP (Double Pussy Penetration/Vaginal Penetration) a few times. Ms. Wells is also well known for her colorful on-screen dialog. She has been at different times represented by Dick Nasty, AMA Talent and Spiegler Girls. She is currently represented by Lighthouse Talent Agency.
