It was Real Housewives of Beverly Hills star Brandi Glanville's birthday over the weekend, and her co-stars took to Twitter to wish her a happy one. So whose messages did Brandi respond to?

Brandi turned 41 on November 16, and Kyle Richards — who is on good terms with Brandi these days — sent her a happy message that morning.

"Happy birthday @BrandiGlanville !!!," Kyle tweeted, to which Brandi responded two hours later, "Thanks, babe!"

Just before Kyle sent that, Lisa Vanderpump — who is not currently getting along with Brandi — had also sent her a birthday message. "A birthday should always be a day of positivity... @BrandiGlanville Happy birthday," Lisa tweeted.

And how did Brandi respond? Well, she didn't respond — at least, not for quite some time. 

The next day, on November 17, former RHoBH cast member Camille Grammer reached out to Brandi, tweeting, "Happy Belated Birthday!" And Brandi tweeted back, "Thank uuiii."

Then, one of Brandi's Twitter followers saw this and wished Brandi could also thank Lisa for her message. "@BrandiGlanville now I will love you even more if you replied to @LisaVanderpump bday wish & put all this nutty Twitter talk to rest," Brandi's Twitter follower named @beesbudoir wrote.

Finally, Brandi obliged. "@beesbudoir @LisaVanderpump thank u," Brandi tweeted. 

So how should we take this? Well, we think it's a good sign that Lisa went out of her way to wish Brandi a happy birthday, and we're also proud of Brandi for thanking her. However, it's clear that Brandi wasn't quick to respond, meaning they still appear to be on the outs.

Do you think Lisa and Brandi will patch things up? And do you think Brandi should have responded more quickly to Lisa?
