This was a long time coming.

Things got downright brutal on last night's "Vanderpump Rules" season finale, with Tom Sandoval jumping Jax Taylor and starting an all-out brawl.

It was a pretty shocking confrontation, one that left Jax covered in blood after getting punched in the forehead. 

For those of you who don't watch the Bravo guilty pleasure, Tom's sometimes-girlfriend Kristen Doute revealed she had hooked up with Jax while she and Tom were dating.

This, obviously, didn't sit well with Sandoval -- who was ticked that Taylor didn't show any remorse for sleeping with one of his best friend's girl.

After the finale aired, Tom called into "Watch What Happens Live" -- where Lisa Vanderpump and Jax were guests -- and was asked if he had any regrets about the beatdown.

"No, I really don't," he said. "I hit Jax in the forehead, I could have hit him in the nose, I could have hit him in the mouth, I could have stomped on him when he fell between the tables. I didn't. I felt like I held back."

Sounds like they'll have some drama to sort out when "Vanderpump Rules" returns for its inevitable third season.
