Kristin Cavallari: I'm in Love With Jay Cutler

Kristin Cavallari may be spending time in the Windy City, but her relationship with Chicago Bears quarterback Jay Cutler is far from gusty.

"I'm in love," she told PEOPLE Saturday night at Las Vegas's The Bank Nightclub while celebrating her 24th birthday.

Sadly, the object of her affection wasn't by her side. He has an excuse though – his team is in the NFL playoffs and played (and won) Sunday against the Seattle Seahawks.

"I want to be there," she said. "I'm bummed that I'm not there and he's not here."

Cutler, however, was there in spirit, and sent a large bouquet of pink flowers to her VIP table at the nightclub.

"Things are really good," Cavallari continued. "I'm just enjoying my personal life and taking a little time away from the public eye, which is why Chicago is great for me. My mom and that whole side of the family is there. And Jay is there. It's nice to be able to hang out with my mom, and, you know, I'm in love and it's been great."

Avril Lavigne Totally Loves Brody Jenner

Brody Jenner and Avril Lavigne have only been dating since February but Avril seems to be totally taken by the reality TV star.

She grabbed the microphone at the Bank nightclub in Las Vegas on Sunday and told the Hills star that she was in love!

A source told the New York Post: "Lavigne and Jenner were having a blast. They were taking shots with friends including Olympic snowboarder Shaun White, grabbing the microphone, shouting, 'Jager shots' and making the crowd go wild."

The 25-year-old pop star even shouted, "I love you, Brody!" into the microphone.

Although Avril and Brody are yet to confirm they're officially an item, they looked like a loved-up couple as they sang the Black Eyed Peas' hit single I Gotta Feeling together.

As another sign of their increasing devotion, Avril and Brody recently had matching lighting bolt tattoos (click here for pictures).

A source said: "They showed up to the opening of Mario Barth King Ink and requested the same tats. They were really excited about it. They held hands openly and were kissing in a corner. Brody didn't leave Avril's side all night."
