Could actor Henry Cavill and MMA fighter Gina Carano be tying the knot soon?

The power couple--Cavill plays Superman in "Man of Steel" and Carano is a former mixed martial artist who has starred in movies like "Fast & Furious 6" and "In the Blood"--have started dating since the fall of 2012, and it looks like the relationship is going strong, even suggesting that wedding bells could be ringing.

The two broke up after Cavill started dating "Big Bang Theory" actress Kaley Cuoco-Sweeting. The relationship lasted only 10 days, however, and Cavill and Carano reportedly got back together shortly.

In an interview published in US Magazine last year, a good friend of the two said that they were instantly attracted to each other, and that "She says they have a good thing going!"

There are a number of signs suggesting that the two are ready to settle down.Despite their busy schedules, they it a point to see each other as often as they can. They have also recently adopted a dog--an Akita puppy from Arkansas breeder Big Bear Akitas.

Meanwhile, despite not being able to do MMA for years, rumors are going around that Carano could still return to the ring. Ultimate Fighting Championship President Dana White said that they are working with lawyers to make the return possible.

White said: "Her lawyers and our lawyers are talking. It's moving along. It should (happen). I mean this guy is a Hollywood lawyer and these guys are always a pain in the ass to deal with. The shit that he calls back and says everyday is literally comical."

Carano's trainer Laercio Fernandes, said that Carano is working out, but not planning on having a UFC fight at the moment: "She's doing great. She trains well, but she has a lot of things to do, like interviews and movies."
