Not acting her usual camera-friendly self, Kim Kardashian was spotted dropping by the gym in Studio City, California on Monday (August 23).

As he headed inside for her regular workout session, the “Keeping Up with the Kardashians” babe kept her head down, shades on and oddly did not show off her beautiful smile as she usually does.

It’s a wonder as to why Kim isn’t smiling today, as “Keeping Up with the Kardashians” fifth season made its debut on Sunday night drawing a record amount of viewers to the E! Channel.

According to Hollywood Insider, the half-hour drama-filled show was the series’ highest-rated and most watched season opener ever and the network’s 2nd most watched telecast ever.

Having been spotted together over the weekend in Costa Rica, Heidi Montag and ex-husband Spencer Pratt are the hot topic as they continue their antics following their recent divorce.

Of the recent trip to Costa Rica, Spencer told People magazine, “I had to bring the puppies down and help them move in. [Heidi] thought I was going to leave, but I’m not. I didn’t want to get divorced … I have nothing in Malibu, I’m homeless, I’m nothing without her.”

Asked if she allowed the visit from Pratt, Miss Montag said, “Everything was calm and going smoothly with the divorce. We were really getting along and it was amazing he was being so thoughtful to help me move. Then things turned.”

Noting Spencer’s recent claims to be shopping a sex tape of Heidi to Vivid entertainment, Heidi tells, “There is no sex tape that exists and there never was. Spencer is trying to drum up press. This is exactly why I wanted to divorce him in the first place.”

Denying allegations that he’s lying, Spencer tells that he does, indeed, have the steamy material, dishing, “I told Heidi … if you don’t want to do the new reality show with me, then I’ll have to release old footage. I can get $5 million from a sex tape, but I really don’t want to do that. It’s not the way I want things to be. Heidi is furious with me but I need to look out for myself.”

While the troubled duo battle it out in Costa Rica, Montag says of her current situation, “I’m going to leave the hotel and get a house because Spencer won’t leave me alone and won’t go back to Malibu right now. It’s just too hard. I still love him, but I can’t stand what he’s doing.”
