John Cena is a 15-time WWE World Heavyweight Champion, but he's also the undisputed champ when it comes to being cryptic on social media.

The "Cenation" leader was back at it again on Monday, firing off a tweet about some "big news" for later this week. The post could mean just about anything, but there has been a lot of speculation that he and Nikki Bella are already engaged and an official announcement could be coming.

WWE 'RAW' Preview & Latest Rumors

Bella created a lot of buzz when she teased that the couple may be engaged already, but she also added even if they were, she won't say for now. It's quite possible that this Tuesday's penultimate episode of "Total Divas' Season 5 could finally reveal the pending nuptials between the two WWE personalities.

Cena has been known to tease things on social media, whether it's a possible match with The Undertaker via Instagram, or his constant cryptic tweets about "defying science" in order to come back in time for WrestleMania. It's possible his latest tweet has to do with the huge event on April 3.

The face of the franchise has been sidelined since January due to a shoulder injury that had to be surgically repaired. Cena was expected to miss several months, but has already been going full-force in the gym and hinting at an early return. It wouldn't be the first time the WWE star came back early from an injury.

Cena is also a part of the "American Grit" reality show which is set to premiere in April, so the announcement could even have something to do with that.
