She then added: "Thank you for the hangover tips. You treat me like a queen!" she gushed on Twitter, seemingly referencing Thompson. Meanwhile, engagement rumors are also running wild as it was reported that Thompson may have popped the question to Kardashian on her 33rd birthday.
While the star likely has something special planned to celebrate today, she already has one birthday bash under her belt: Her friends and family threw her a surprise party on Sunday in Los Angeles.

Khloe and Tristan are getting serious and have talked "about both a wedding and a baby", a source told People.
She said: "Tristan and I definitely talk about starting a family. We could start at one and we could grow from there", she reportedly stated in her long-running reality series with her family.
Thompson has a 6-month-old son named Prince with ex Jordan Craig. Khloe's youngest sister, Kylie, sported an Attico rainbow-striped sequined dress, which she paired with strappy black heeled sandals.
