Months after Glanville starred alongside Kenya Moore on Celebrity Apprentice, and continuously feuded with her fellow Real Housewives star, Taekman posed for red carpet photos with Moore, telling her fans how "gorgeous" Glanville's nemesis was.

"I got to met the gourgous @KenyaMoore last night at the @ccicanine event hosted by the ever gracious @IanZiering," Taekman wrote on Twitter on Friday.

Around the same time, Moore shared another photo of herself and Taekman, in the comments section, a fan noted, "That's Brandi's best friend. @BrandiGlanville Brandi will be pissed @TheKenyaMoore."

In the photo below, Moore is seen commenting on the fan's reaction, writing the word, "mistake."

Just three months ago, during an appearance on Extra TV, Glanville opened up about her ongoing tension with Moore, revealing she was the one who initiated feud when she called Moore "desperate" after seeing her pressure her former boyfriend, Walter, to marry her.

From there, Moore took their feud one step further, claiming on Celebrity Apprentice that Eddie Cibrian, Glanville's ex-husband, left her for the "younger, prettier" LeAnn Rimes, and noting she loves Rimes' music.
