The R&B singer and Vaughn played best friends in the hit 1990s sitcom, but off-screen, their friendship was non-existent. In a 1998 interview with Vibe magazine, Brandy spoke openly about their rivalry, saying, "I think she's very funny, very talented. I just feel like she wants to be in the position I'm in."

"People tell her, 'You're the reason why the show's successful.' And she's told me that before. And she's called me a b**ch - to my face in front of a lot of people... She wakes up and looks at herself in the mirror and gets disgusted. I don't."

However, on Saturday (19Dec15), Vaughn decided to publicly put the past behind them, with a touching post on Instagram.com.

"@4everbrandy I'm proud of you," Vaughn wrote. "We been threw are (sic) ups and downs , high and lows ... But at the end of the day I had to learn in find myself why not be friends when we're both talented, Why call you names when your (sic) just an amazing person."

She continued, "I believe in who you are and who you are working to be. We are all works-in-progress. I care about your life and your happiness... I care about you as a person. We are spiritual siblings, you and I."

"I apologize for anything Negative I've ever done are said to you ....sorry this had to be on social media , I just want the world to see that I've grown out of my comfort zone."

Vaughn concluded, "No matter how or if she respond know that the Universe will continue to bring me growth and happiness because that is what im putting out there... Congratulations on every thing you've accomplished... Love you beautiful."

Brandy took note of Vaughn's online apology, and wrote an equally heartfelt message in return, saying, "My heart is truly moved. Thank you God. This is a blessing... I would love to start a new friendship with you with new heads on both of our shoulders. It will also be great to work together again. Without you, Moesha would not have lasted as long as it did."
