Rockstar revealed the big news in a Sunday Instagram photo in which she's posing with her new fiance and showing off her unusual engagement ring.
"Diamonds are a girl's best friend but moldavite is a witchy woman's best friend! #isaidyes #engaged," Rockstar captioned the picture.
Rockstar's groom-to-be also shared his excitement on Twitter by writing, "Thank you everyone for the congrats and well wishes!!!! I love you all and want to go like and reply to every one of you but there are so many!!!! @Mrs_ARockstar and I feel the love. thank you all very much!!!"
Rockstar and Chris have received many congratulatory messages from fans and fellow former Big Brother houseguests.
For example, Chris "Swaggy C" Williams -- who is engaged to Season 20 BB houseguest and Rockstar's pal Bayleigh Dayton -- tweeted, "Me, Bay, Fes & Haleigh planned to be in Baltimore tonight to surprise Rockstar but we couldn't make it. We all literally cancelled last minute. Feel so BAAAAD."
While Rockstar received a lot of love and support from her followers, she also had to read some nasty comment from haters and social-media trolls.
The Maryland native chose to address all the backlash in a Tuesday tweet.
"Response to comments on my engagement," Rockstar began.
"'I thought she was married '- I was to my daughters' father, it's called divorce. 'I thought she was gay.' - Well I love rainbows and gays, but I'm a cisgendered female that just loves the [eggplant emoji]. 'Ring cost $39' - actually free from a cereal box."
