It shouldn’t have gone so far – or become so ugly.

So says Real Housewives of Beverly Hills star Kyle Richards of her nasty blowout that left her on the serious skids with sister Kim in the season finale.

“The events that transpired that evening were quite unfortunate and should never have occurred on or off camera,” the reality star, 42, said in a statement released Friday by Bravo. “There are a lot of elements to the story that viewers didn t see.”

She adds: “This has been difficult for our entire family as we both said and did things that we regret. My sister and I love each other very much we want to move forward and put this behind us.”

In the clash in a limo, Kyle called her older sister, 46, an alcoholic and threatened to revoke any aid – apparently financial – that she and her husband provide. Kyle also said she’d stop covering for Kim amid allegations of alcohol.

Kim and Kyle will discuss the matter further in a reunion special hosted by Andy Cohen on Jan. 27 at 9 p.m. on Bravo.
