Katie Maloney and Tom Schwartz reportedly experienced marital issues during filming the sixth season of Vanderpump Rules.

Although the couple has been married for less than one year, they are well out of the honeymoon stage and possibly headed for a split.

"Katie and Tom are on the rocks," an insider revealed to Radar Online on Wednesday. "Katie is with Stassi [Schroeder] and the 'Witches of WeHo' 24/7 and isn't focusing on her marriage. Tom can't stand Katie with the mean girls all the time."

Maloney and Schwartz tied the knot in August of last year amid filming the fifth season of the Bravo TV reality show.

Prior to her engagement, as fans may recall, Maloney dealt Schwartz with a proposal deadline, which she later took back.

"When that came about, I was fed up and really frustrated," she explained to Cupid's Pulse. "I was like, 'Okay, well, how many blows can I take and still be patient and understanding and work at this with you?' There were all these bombs coming out of left field!"

"I had to completely turn my attention and priorities towards our relationship and assess everything," she added in a blog.

"Rebuilding my relationship was the most important thing to me. So in order to move forward, both in head and heart, I had to forgive everyone. Not for them but for me... For me, I cannot move forward and grow and learn if I do not swallow my pride and forgive and accept. I did this for myself and for my relationship. Tom on his own was making moves to preserve our relationship, and this was my contribution to our growth."
