The reality star had called an end to publicly sniping with Rimes in December, after having chided the singer for referring to Glanville and Cibrian's sons as "my boys".

However, Glanville has now attacked Rimes and Cibrian once again, after stories appeared in the press about the couple moving into a large estate.
"Ok Im super excited my kids are moving into a mansion but I want to throw up in my mouth and swallow it- having to keep hearing about it," the Real Housewives of Beverly Hills star tweeted.
Rimes did not respond directly to Glanville, but did post a cryptic message on her Twitter account that could have been a reaction to the insult.
"Oh the bulls**t! Laughing," the musician wrote.
Tensions have run high between the two for years, stemming back to Cibrian leaving Glanville in 2010 to begin his relationship with Rimes.
Rimes recently admitted in a television interview that she has regrets about beginning her romance with Cibrian while both were still married.
"I wish I handled it differently because I wish I could have been better for me, for Brandi, for [my ex] Dean, for Eddie, for everyone else," she said.
Cibrian and Rimes married in April 2011 in California.
