Jaden Smith was a guest at Kendall’s lavish birthday party at the Jenner/Kardashian family’s home...and that, sources say, is where he fell in love.

“Jaden is hopelessly infatuated with Kendall, despite their age difference and the fact that she towers over him,” a source said.

“What Jaden lacks in height and age, he makes up for in confidence.

“But Kendall isn’t interested. Although she thinks Jaden is adorable and a cool friend, that’s where it ends. She wouldn’t date him in a million years.”

Sources say Kendall’s momager, Kris Jenner, is happy about Jaden’s crush on her daughter.

“Kris is salivating over the thought of turning Kendall and Jaden into the fam­ily’s next power couple,” said the source.
