Rumored to be dealing with a little sibling rivalry, Kim Kardashian may not be getting her wish to be engaged to Reggie Bush this holiday season.

Tabloids reported that the E! reality beauty would’ve been getting a ring over Christmas, but sister Kourtney put an end to it.

 

One source says, “There’s always been underlying tension because Kourtney feels like she’s been playing second fiddle to Kim for so long. She was hoping that the last days of her pregnancy and the first few weeks with her newborn would be all about her.”

Adding, the source spilled, “Kourtney screamed at Reggie, ‘You can’t do this to me!'”

The insider continued, “Kourtney is extremely hormonal right now, and emotions got the best of her. Reggie was stunned and caught completely off-guard. Reggie doesn’t want to battle Kourtney, so he backed off to keep the peace.”

But that doesn’t mean there won’t be wedding bells anytime soon. “Now he’s planning on asking for Kim’s hand in marriage in early 2010, after Kourtney’s baby hubbub has died down.”
