"Hope everyone had a merry Christmas, we did," she tweeted. "Headed to Nashville w/ the fam to see my dad and bonus mom. Should be fun!!"
The couple, and a very smiley Jake Cibrian, were photographed catching their departing flight from LAX earlier today for the week-long vacation.
Brandi also acknowledged that she'd be without her sons, tweeting, "Kids are off to Nashville with dad for the week and I am off to the gym to see my trainer! So glad Christmas is over! #decompress"
Glanville and Rimes got into a Twitter war recently after the country singer wrote, "Flying out with my boys in a few hrs. Love that it's a family tour weekend. It's always more fun when they are with me."
That didn't sit too well with the Real Housewives of Beverly Hills star, who responded by tweeting, "Someone is trying 2 get under my skin by calling MY children 'her boys' Sooo transparent! They R MY boys, Eddie Boys and ur step-sons... 4 now."
