She's logging some serious frequent flyer miles!

Khloe Kardashian landed back in LA after spending time with her boyfriend Tristan Thompson in Cleveland, and the reality dressed cozy for her flight in Givenchy track pants. We don't see a ring on her finger yet, but we don't think it will be much longer before the NBA star pops the question!

"Khloe and Tristan are doing so great and have an incredible relationship. There could be an engagement this summer," a source dished to ET.

Not that the Revenge Body star is pressuring her man!

"Khloe doesn't need a title to make their relationship real and she doesn't want to mess up how perfect it is now. She's already done the marriage thing [with now ex-husband Lamar Odom]. Getting engaged is not something she's sitting around stressing about. If it happens, it happens, but it's not something she's stressing about right now," the source added.

The E! starlet really wants babies in the near future, though.

"Khloe is dying to have kids. It's something she's wanted for years, even with Lamar. Tristan just had a baby and Khloe sees how wonderful of a father he is. Khloe sees how close in age Kim, Kourtney and Rob Kardashian's children are and she wants the same. It's certainly a thought in her mind, but she isn't putting pressure on Tristan to give her that right now [either]. She doesn’t want anything to mess up what they have going on," the insider revealed.

She's always been our favorite, so we hope she gets her happily ever after!
