Sunday night was a hot date night in Miami!

Exes Kim Kardashian and Reggie Bush both decided to step out with their new loves for a romance date night Sunday in Miami -- right next door to each other.

Kardashian enjoyed dinner at Prime 112 in Miami Beach with boyfriend Kanye West. Kardashian, 31, flaunted her cleavage in a sexy cutout black dress while holding hands with West, 35, who wore black leather plants.

Bush also stepped out with his pregnant girlfriend Lilit Avagyan, who is barely showing, to dine at the nearby Prime Italian. The 27-year-old Miami Dolphins player confirmed last week that he and Avagyan, who have been dating for about a year, are expecting their first child together. The dad-to-be told Florida's Paul and Young Ron Morning show that a baby is "the most special gift to a man and to a woman. I look forward to it, and to building a family."

Kardashian and Bush were on-and-off for several years, but called it quits for good in March 2010.

The rapper has been dating the reality star for seven months. Kardashian is still engaged in a heated divorce battle with her estranged husband Kris Humphries, but she believes West is the one. "Anything I'd be in now would be a permanent relationship," she told The View in September about her relationship with West. "At the space that I am in life now, kids are definitely something I want," she added. "I think I wanted that before. I think I fell in love so quickly and wanted that to be my life so badly but I just didn't take the time to find someone."
