Power couple and newlyweds Kim Kardashian and Kanye West have reportedly put off their daughter's first birthday party.

Little North will turn one tomorrow (Sunday, May 14), but it looks like the family won't be marking the landmark occasion until next week.

A source told E! News: "They are throwing her a big party next weekend and Kourtney [Kardashian], Khloé Kardashian and kids coming home for it."

Kimye spent the last week enjoying their "second honeymoon" in Mexico, after trips to Ireland and Prague following their wedding in Florence, Italy, on May 24.
