But we're sorta not surprised.
Kylie and Cody, also 14, met for the first time earlier this month at the Hollywood premiere of Breaking Dawn: Part 1 when she and her sister Kendall interviewed the pop singer for Ryan Seacrest's On Air radio show on 102.7 KIIS FM.
"You're my rumor boyfriend on Twitter," Kylie said to Cody. "Nice to finally meet you."
Kendall later said to camera, "I think Kylie should date Cody Simpson because they'd be so cute together."
Kylie even went so far as to proclaim, "I'd marry an Australian."
After the premiere Simpson tweeted to the Jenner girls, "had a real good time on the red carpet with you last night. and see ya soon I hope!"
US Weekly claims Cody and Kylie are definitely dating. "They are a couple!" a source told the mag. "They are so cute together."
Reps for Kylie and Cody did not immediately comment for this story.
