Timothée Chalamet raised eyebrows after he missed girlfriend Kylie Jenner's 28th birthday party. Rumors swirled that the pair split after Jenner celebrated sans her actor boyfriend and, instead, with just her friends and family. However, a source tells Us Weekly that Jenner and Chalamet, 29, are "still together." Earlier this month, Jenner was joined by her loved ones for a sunflower-themed get-together in honor of her special day. The festivities included an art station where Jenner and her guests painted portraits of the reality star as the Teletubbies sun.
