Kim Kardashian and Reggie Bush ended their three-year relationship in 2010, but that does not mean they never see each other. The former couple bumped into each other on Monday while in West Hollywood.

The reality star headed to Ed’s Coffee Shop to get an omelette, and the Detroit Lions player happened to be there with his 26-year-old fiancée, Lilit Avagyan.

"It seemed uncomfortable,” a source tells Us Weekly.

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

After the awkward encounter on Monday, Kardashian headed to high-end baby boutique Bel Bambini. Bush and Kardashian have both moved on since 2010, though they reportedly reconnected after her marriage to Kris Humphries, which lasted 72 days, ended.

Kardashian is now engaged to rapper Kanye West, who proposed to her for her 33rd birthday in October. They have a daughter, North West, who was born last June. Bush and Avagyan are also engaged and have a daughter, Briseis. When Bush began dating Avagyan, she drew comparisons to Kardashian, as both are of Armenian heritage, have dark hair, and curvy figures.
