WWE news: John Cena, The Undertaker and the longest-serving superstars revealed

If there's one thing we know about Vince McMahon, it's that he demands loyalty from his wrestlers. 

Pro wrestlers might have a short career in the grand scheme of things, meaning the very best usually stick around in WWE. 

If you show the boss loyalty, he'll show it back to you.

Just look at his relationship with The Undertaker. 

Those two would go to war for each other. In fact, we can almost picture them in the trenches together, fighting side by side. 

But 'Taker isn't the only wrestler who could be considered loyal to WWE and there are plenty of other long-serving performers in the company. 

Let's take a look at the 10 stars who have been on McMahon's roster for the longest.  

10. Natalya | 13 years

Natalya is the second longest-serving female star currently under contract in WWE. 

As the daughter of Jim Neidhart, wrestling runs in the family and for that reason, it's hardly a surprise she's been with WWE for so long.  

9.  Kofi Kingston | 14 years

Kingston signed a developmental contract with WWE in September 2006 at the age of just 24 - and he hasn't looked back since. 

Beloved by fans as a member of the popular New Day tag team, he even had a famous run with the WWE Championship in 2019. With that win, he became a grand slam champion.  

8. R-Truth | 16 years (two runs)

One of WWE's most loved stars, R-Truth isn't exactly a main-event player, but he's comedy gold every time he's on screen. 

The current 24/7 Champion has had two runs with the company, the first coming between 1998 and 2002 as K-Kwik before returning in 2008 with a new ring name. 

In total, R-Truth's two WWE runs combine for 16 years.
