"Dear #Family, I am overjoyed to announce my engagement to my angel on earth, Michael F," she shared on Instagram.
"I am here to tell you that you can find love after tragedy. That a death of a soulmate does not mean the death of you. My family, friends, and my Linkin Park brothers welcome him to the family with open arms.
"I will continue to honor Chester and continue my life's mission to make his passing not in vain. To all Suicide Loss Survivors, you CAN be happy again. You CAN have space in your heart for grief, joy, happiness, sadness, and love.
"Thank you ALL for your continued love and support (sic)."
Talinda's friends and followers were quick to send congratulations to her after she revealed her happy news and to show their support for the new romance.
Linkin Park's Mike Shinoda wrote: "I've already congratulated you both in person, but congrats again, ha! All our love and support!"
And Vicky Cornell, the wife of Soundgarden's Chris Cornell - who was a close friend of Chester and died by suicide just two months before him - wrote: "Congratulations! Sending you all so much love. (sic)"
