Courtesy of Chicago Cut SteakhouseKate Upton had quite a birthday!
The blond bombshell was joined by Justin Verlander and pals for a dinner at Chicago Cut Steakhouse earlier this week to celebrate Upton's 22nd birthday, but the fun didn't stop there!
Kate continued her birthday celebration at the Underground in Chicago, an eyewitness tells E! News. Upton arrived at the after-hour club at around 2 a.m. Thursday morning with her boyfriend and one of his Detroit Tigers teammates Phil Coke.
According to the insider, Upton was looking very stylish wearing a red dress and was very friendly with staff and guests.
"He was trying to be low-key, but she was up dancing with a fun group," says the eyewitness. "They were the most fun group in the club that night."
Upton was also spotted being affectionate with her boyfriend. They were all drinking Grey Goose cocktails and enjoying the house music played by DJ Tony Arzadon. "It was a really fun night," says the eyewitness.
Also at the Underground in Chicago that night was Backstreet Boys members Nick Carter and Howie Dorough, who came in with Nickelback lead singer Chad Kroeger and a group of friends at around 1:40 a.m. Howie left early in the night, while Nick left at 3 a.m. and Chad stayed until closing. Nick and Chad seemed to be having a great time, dancing on top of podiums and were interactive with crowd, according to the eyewitness.
Sounds like a pretty awesome time!
