Sometimes, bygones will never be bygones.
Sending Brandi Glanville Mother's Day flowers only resulted in another diss as LeAnn Rimes' feud with the reality star shows no signs of abating.
As a peace offering of sorts, Rimes sent The Real Housewives of Beverly Hills star a bouquet last weekend ... only to receive a passive-aggressive reply.
On Twitter, natch.
"I thanked @leannrimes on twitter 4 my flowers," she wrote. "Our relationship is that we still don't even say hi at baseball. I don't have her number. That's it."
