Watch : Best Believe Kylie Jenner is Bejeweled as She Celebrates Her 29th BirthdayKylie Jenner is feeling purr-fectly marvelous about her birthday. With her 29th birthday coming up on Aug. 10, the Kylie Cosmetics founder kicked off the celebrations by sharing an inside look at her princess kitty-themed early birthday party, complete with all the bejeweled vibes that were ready to make the whole place shimmer. And Kylie herself kept the “kitty” theme going in a short pink halter-top dress with a plunging neckline that she paired with a furry headband, pink boa and pink feather kitten heels. She posted a video of herself walking around in the heels with the caption, “My pre bday princess kitty party.” And, of course, she matched her nails to the pink of her dress.
