Kanye West Loses Cool Following Awkward Run-In With Kim Kardashian, Reggie Bush (PHOTO)

Kanye West was photographed lashing out at a paparazzi photographer in Miami on Sunday night following an awkward run-in with his girlfriend Kim Kardashian's ex-boyfriend Reggie Bush.

West, who enjoyed a meal with Kardashian at upscale restaurant Prime 112, was seen lunging at the unsuspecting photographer upon his exit as the reality TV personality watched. The camerawoman had allegedly asked 35-year-old West if he had congratulated Bush on his girlfriend Lilit Avagyan's pregnancy, according to RadarOnline.com.

Bush, 27 and 25-year-old Avagyan are expecting their first child, and the two were seen enjoying a meal next door to Kardashian and West. This likely infuriated the rapper, as some recent reports suggest that Kardashian, 31, is still in love with the NFL star.

"Kim and Kanye had a very discreet dinner in a private room with the curtains drawn at Prime Hotel while Reggie was with his girlfriend across the street at Prime Italian. Kim and Kanye got there around 5:30 p.m. and made a big scene when they exited two hours later," an eyewitness reportedly told In Touch magazine.

"They were yelling at photographers and one of them even asked Kanye about Reggie being so close by; he didn't seem too happy about it. Both Kim and Kanye looked a bit stressed out," the source went on.

Kardashian was reportedly "very upset" upon learning that Bush, who she previously dated for three years, is expecting a child with Avagyan. The reality TV personality reportedly still clung to the hope that they would one day reconcile, according to dubious reports from RadarOnline.com.

"Kim is very upset that there are reports out there Reggie has gotten Lilit pregnant," a source reportedly told Radar.

"Kim had pressured Reggie for a very long time to get married while they were together because she wanted to have a family with him. Reggie just thought that Kim placed too much of a priority on her fame and reality television though and he wanted none of it. Reggie was a part of the Kardashian family for over five years and deep down Kim has always held out hope that they would end up together, even though she married Kris Humphries," the source explained.
