Kourtney Kardashian reportedly is ready to take her relationship with Scott Disick to the next level. A source tells Fox News that the couple has visited Sharon Sacks, a wedding planner previously hired for Kim Kardashian's lavish wedding to New Jersey Nets' Kris Humphries.

"About a month ago they visited celebrity wedding planner Sharon Sacks together just to discuss some ideas," the source reveals to the publication. "Nothing was set in stone, but Kourtney is definitely exploring the idea, which is a huge step for her."

Although they consult an internationally sought-after event planner for the nuptials, the insider insists that "Kourtney will likely be very low key when it comes to her wedding." The source adds, "Don't be surprised if it's not even on TV. That's Kim's style, not hers."

Kourtney and Scott have been together for five years, going through several breakups and makeups before they reunited in late 2009 after she learned she was pregnant with their first child. In 2011, they were rumored getting engaged secretly.

The couple welcomed their son, Mason Dash Disick, on December 14, 2009. The reality TV star gave birth to their second child, Penelope Scotland Disick, in natural birth on Sunday morning, July 8 at Los Angeles' Cedars-Sinai Medical Center.
