Although reality star Kim Kardashian says she is completely happy with boyfriend Kanye West, she feels jealous about her ex-flame Reggie Bush becoming a father, according to reports.

Reggie Bush has been dating Lilit Avagyan for nearly a year, and according to In Touch Weekly, she is now three months pregnant. The Kim Kardashian look-a-like is said to be “extremely excited to become a mom, even though it wasn’t planned,” a friend of Bush’s told In Touch. And Bush is said to be “excited and can’t wait to announce it!"

Kardashian and Bush were together for around three years before breaking up in 2010.

"Her fame is just a little too much for him to handle," a source told "She travels the world and has created brands. He just can't keep up. They are unsure of what will happen in the future."

And now, it seems Kardashian is not too happy about Bush’s good news. A source told Radar Online that "Kim is very upset that there are reports out there Reggie has gotten Lilit Avagyan pregnant. 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.

She feels it is a slap in the face that Reggie would consider having a baby with this woman when he wouldn't with her.”

Kardashian recently gave an interview to Tatler magazine, calling West her “best friend” and saying “I can’t even think about being with anyone else than the man I’m with.”

But is that really true? Or does she want to make Bush jealous with her public displays of affection with West? The source went on to say that “publicly, Kim is putting on a very brave face, but she just isn't happy with the status of her personal life. Seeing Reggie move on like this makes her all the more determined to marry Kanye and prove to him she's moved on too — even though she obviously hasn't!"
