Vanderpump Rules stars, Jax Taylor and Brittany Cartwright, are reportedly "unhappy" in their marriage just a month after tying the knot.

At the beginning of their relationship, Jax was unfaithful to Brittany but worked hard to put his bad-boy ways behind him.

"Brittany wanted to have this magical and over-the-top wedding so that she could have a dream wedding that would play out on TV," a cast insider told Radar Online. 

It is also being reported that Jax is fretting because the couple did not sign a prenup:

"Jax is freaking out about money now, too. Now that they are married, all of his money is hers and all of her money is his and it has been causing some major issues because she loves to spend."

The source added: "And to make matters worse, they did not get a prenup…Everyone thinks that this was such a huge mistake."

Oh, dear!
