The 38-year-old WWE wrestler and 32-year-old former WWE Divas champion discussed tying the knot in a preview for Total Divas Season 5 released Monday.
"We can talk about marriage," Cena tells Bella in the promo.
Bella told E! News in September she and Cena keep their romance alive by making time for date night every week. She also discussed her future with the wrestler in an interview with OK! magazine the same month.
"It's so amazing," she said of their relationship. "We both know we want to be together forever. In the upcoming season he's more open to marriage."
Cena and Bella have been together since 2012, and are considered a power couple in the WWE world. Bella and her twin sister, Brie Bella, also a wrestler, have starred on Total Divas since 2013, and will return Jan. 19 at 9 p.m. ET on E!.
