Kim Kardashian has broken her silence on Wednesday, April 6 following her brother, Rob Kardashians engagement to Blac Chyna but sadly it was not to address the situation but to announce her appearance at the upcoming Vogue Festival.

As  we reported, Rob proposed to Chyn on April 5 after just a few months of dating, but his mom Kris Jenner and his five sisters, all of whom are currently on vacation in Colorado, have stayed silent about the engagement.

In her first tweet since the news broke, Kim posted a link on Wednesday to buy tickets for the 2016 Vogue Festival, adding, "So excited to be in London and speaking at the Vogue Festival in May! See you guys there!”

The rest of the Kardashian-Jenner clan are yet to comment about Chyna joining their family. Kris, however, has since promoted Kylie’s "Paper Magazine" shoot and Kendall’s Webby Award nomination. Meanwhile, Kourtney quoted a passage from the children’s book "Goodnight Moon".

As for Kylie’s boyfriend Tyga, who’s also the ex-fiance and father of Chyna’s three-year-old son, he congratulated her and Rob following their big announcement while Chyna's mother, Tokyo Toni slammed the TV family telling them they were not invited to the wedding
