Billie & Kristen Explode Into Vicious Feud After Lee Replaces Doute On 'VPR'!

The beef between Billie Lee and Kristen Doute exploded into a nasty feud after Lee effectively took Doute’s job as full-time cast member on Vanderpump Rules.

As RadarOnline.com previously reported exclusively, Lee, 33, will be replacing Doute, 34, who is being demoted on the hit Bravo show due to her lack of drama. But if it’s drama the network is thirsty for, look no further than the two stars twitter accounts.

On Monday, Lee tweeted her displeasure about not being invited to a co-worker’s event.

“When yo coworkers don’t include the only trans girl in GIRLS night at your own job! On the night you work! #rudeAF #TransIsBeautiful,” she posted.

“This was not a birthday at someone’s house. This was an event called GIRLS night at my job where I work and on the night I’m scheduled,” she continued in a follow up tweet. “It’s not a matter if you like me or not! I work there.”

Doute saw the messages, and couldn’t resist adding her two cents.

"It's not your event," she wrote. "Don't make this about something it's not. #NoH8."

That led to Lee snapping back at Doute, “Boo you don’t work there so why are you speaking?”

Doute, 35, has yet to reply to the question. As RadarOnline.com reported exclusively, Doute is being downgraded to a ‘friend’ of the cast next season, as her stable life with her low-key boyfriend of three years Brian Carter has become boring for viewers.
