Kourtney Kardashian is said to be fuming over thoughts she will be “overshadowed” by sister Kim on her wedding day.
Speculation is rife the eldest sister of the Keeping Up with the Kardashians clan is engaged to Scott Disick, the father of her two children.
Kourtney’s younger sibling Kim, 33, is reportedly marrying Yeezus rapper Kanye West, 36, in Paris this summer and it is claimed a potential feud is now brewing.
“She wants her wedding to be just as spectacular as Kim’s,” a source told Radar Online, noting Kim’s 72-day marriage to basketball player Kris adds fuel to the fire.
“Kourtney has already seen Kim have an over-the-top wedding with Kris Humphries and now she’s watching her sister turn her Kanye West West date into another big affair and she’s getting mad that her own wedding is going to be overshadowed,” the insider explained.

Kourtney would be marrying for the first time if she ties the knot with partner Scott, who she has been in a relationship with since 2006.
And she purportedly can’t stand the idea of having her sister steal her thunder.
“For a really long time Kourtney has felt like she is living in Kim’s shadow but she doesn’t want her wedding to be second to Kim’s THIRD trip down the aisle,” the source detailed.
“Everyone knows that Kim is the most popular sister and Kourtney really wanted her wedding to be special, so she’s not planning to let Kim steal her spotlight now.”

Kourtney has previously spoken about the immense love she has for her siblings, but she confessed rivalry existed in the past.
“When we were growing up, I could boss Kim around! I was such a bossy older sister!” she told Now magazine, before noting middle sister Khloe has taken on a new role in recent years.
''Now I think I sometimes play the younger sister, while Khloe plays the eldest. Khloe, a lot of the times she'll try to act like she has it all going on and she's so tough. It's really funny. We all kind of have our roles - it's cool.”
Life & Style recently reported Kourtney and Scott are due to wed in Mexico, but the couple remain mum on rumours they are betrothed. Subsequent reports suggested they never became engaged and no upset exists between the Kardashian sisters.
