Reggie Bush's fianceé Lilit Avagyan has always been compared to the NFL's baller ex-girlfriend Kim Kardashian. 

On Tuesday, Avagyan stepped out in Los Angeles with Bush flashing her huge rock as the couple was spotted buying a child car seat at Bel Bambini. Her ring is not quite as big as the reality star, but the diamond is flawless, nonetheless. See photos here:

Avagyan looked casual for the shopping trip, wearing a tight-white shirt and jeans, showing off her figure that has also often been compared to Kardashian's. 

Bush famously dated Kardashian on-off for several years before officially breaking up in March 2010. The Detroit Lions running back has been dating the 26-year-old dancer for almost two years.

Bush and Avagyan welcomed the adorable little girl Briseis in May 2013.

"She's amazing. She's so beautiful. I love her to death. It's just been an amazing experience so far so I'm very excited - just being a father," he told Us Weekly last year.

While Bush is extremely happy, he said he was nervous at the same time. 

"This is a new experience for me, you know. Getting the chance to be a father and bring a little one into this world, it's a blessing, but at the same time, I'm excited, I'm a little nervous...all the different feelings that go into being a first-time father," he also told E! News at the time.
