Cena and Bella began dating in November 2012, four months after the 15-time World Champion officially divorced his then-wife Elizabeth Huberdeau after nearly three years of marriage.

Their relationship has been one of the focal points of the WWE's E! Network reality show, "Total Divas," and Bella has recently expressed her desire to marry Cena and have children with him.

"Marriage and kids. I think I could sacrifice kids for him but I do want that ring one day, I want to be Mrs. Cena," Bella told E! News earlier this month. "Our life has become one and we make decisions together but I think I want that bling to walk around with."

While their relationship has flourished outside of the ring, it's in the squared circle where Cena and Bella truly thrive in front of the WWE Universe.

It's an interesting concept as the fans know the two are dating yet Cena portrays the top babyface in the company while Bella's character is the top heel in the Divas division.

Cena won the United States Championship at WrestleMania 31 in March by defeating Rusev and he has revitalized the title through open challenges on Monday Night RAW and five-star caliber bouts.

Cena's latest rivalry with Kevin Owens is a candidate for 2015 Feud of the Year and saw the Cenation leader clash with the former NXT Champion in three stellar matches.

The U.S. Champion has since moved on to a feud with WWE World Heavyweight Champion Seth Rollins, though he sustained a broken nose after catching a knee to the face from The Architect two weeks ago on RAW.

Though he's injured, the WWE is pushing toward a title-for-title clash between Cena and Rollins at SummerSlam on Aug. 23 at the Barclays Center in Brooklyn, so it's expected he'll return to action soon.

As for Bella, she is on Day 260 of being Divas Champion, which is 35 days shy of AJ Lee's record for longest reign atop the division.

The Bella Twins have joined up with Alicia Fox to form Team Bella and are currently feuding with Team B.A.D. (NXT Women's Champion Sasha Banks, Naomi and Tamina) and Team PCB (Paige, Charlotte & Becky) as part of the Divas Revolution.

While Cena and Bella are very different from one another on-screen, their relationship has prospered behind the scenes.
