Talk about moving fast. It looks like it'll be a late summer wedding for Kylie Jenner and Tyga who, sources say, just got engaged!

Tyga, 25, is apparently all ready to put a ring on 17-year-old Kylie, but just one thing is standing in their way.

“Kylie accepted Tyga’s proposal a few weeks ago and made the announcement to her family,” a source told In Touch. "She wants to get married as soon as she turns 18 in August.”

The insider also says that Kylie just "can't wait" to tie the knot with her older man.

“She told her friends that Tyga gave her a ‘symbolic ring’ for now and she isn’t showing anyone until her birthday, when she’ll make an official announcement… They’re tired of hiding,” the source added.

Hopefully Kylie is ready to grow up fast, as marrying Tyga will make her a step mom to the rapper's son with Blac Chyna, two-year-old King Cairo. We're just going to say that again: Kylie could be a STEP MOM.
