The reality starlet Kimmy cakes and Kanye West went to Oklahoma with 2-month-old daughter North on Saturday for the funeral for the rapper’s grandfather, Portwood Williams Sr., who died on Aug. 10 at 98 years old.
“That’s why they weren’t at [sister] Kylie’s birthday,” a source confirms to PEOPLE. “They brought North, too. Her first trip.”
Because they weren’t able to celebrate Jenner’s Sweet 16th party on Saturday, the couple – who welcomed their new addition on June 15 – sent some very special guests in their replacement: hip-hop artists Drake and Big Sean.
The rest of the family, including Khloé Kardashian, Kourtney Kardashian, Kendall Jenner, and parents Kris and Bruce Jenner, were in attendance at the Alice in Wonderland-themed bash, reports E! News.
