Model Charlotte McKinney had a rough ride on Monday night’s “Dancing with the Stars.”

The Carl’s Jr. Super Bowl commercial star made mistakes in her jive performance with dance partner Keo Motsepe, and suffered the consequences, tying for the lowest score of the night with a cast mate, singer Redfoo (both earned just 22 points out of a possible 40).

After the show, McKinney admitted exclusively to FOX411, “It was definitely extremely hard with everyone here.”

And when asked about her “DWTS” future, dance pro Motsepe shrugged, “I don’t know yet.”

With Motsepe by her side, however, McKinney insisted on accentuating the positive, saying, “But we had the best time and gave it our all and we can’t wait for next week.”

There will be no elimination on the hit ABC reality show until all the competitors dance again next Monday, and that’s probably lucky for McKinney after judges pointed out her live TV missteps.

They did praise her positive attitude, however, and backstage after the “DWTS” taping, she was just as upbeat, saying, “I had so much fun.”

She commented on the judging, “I knew it would be like this. I saw it coming and it’s all in the way you take it, and I’m having fun with it and you can’t take anything too serious.”

While McKinney said during the show, “I want to show America there’s more to me than just boobs,” TV rehearsal clips showed her comically holding such items as melons, flowers, and cereal over her chest.  

Viewers also saw her partner Motsepe duct taping her breasts down so she could dance better in rehearsal.

Producers “wanted to play that up, ‘cause that’s how I got here in the first place. But I think as we go on, you’ll see a lot more to me.”

She also told FOX411, “I really joined this show to show I can do more than modeling and show another side to myself. That’s what I’m looking forward to on this show -- and laughing at things that are flaws and assets and joking around.”

McKinney, whose debut costume was a sexy blue bra like top and short feathered skirt, noted that producers “wanted the first outfit to be a little crazy but I think as we go we’ll tone it down and show different styles for sure.”

She is looking forward to wearing an elegant ball gown, and added, “We’ll still put a slit in the ball gown. It will be gorgeous and I look forward to doing the different dances.”

The blonde model hopes to improve her dancing by “just putting the time and effort into it. It’s been really difficult for me because I’m also working through all this. I’m shooting-- I have auditions and trying to balance it out and not get too stressed and overwhelmed, just taking it day by day.”

Don’t expect her to do another Carl’s Jr. commercial, however: “I think once you do it, you do it, and you’re done. But you never know. We’ll see.”

Meanwhile, McKinney won’t talk about her romantic status, saying only, “I’m enjoying myself. I’m dating. Leave it at that.”
