Sailor Brinkley-Cook beams with pride as she flaunts her dance-honed body after DWTS rehearsals

Sailor Brinkley-Cook made a dazzling debut when she hit the ballroom with professional dancer Val Chmerkovskiy on Dancing With The Stars.

And now, with just two days until her next routine in front of millions of viewers, the 21-year-old model looked to be in great spirits following more grueling rehearsals inside a Los Angeles studio.

The daughter of legendary supermodel Christie Brinkley was all smiles during her walk to her car, which included stopping to pose for pictures with adoring fans.

Reaping the benefits of all her hard work, the New York native flaunted her dance-honed figure in beige leggings and a matching sports bra.

She also donned white sneakers and pulled her long blonde tresses back into a  braided ponytail.   

At one point, Brinkley-Cook unexpectedly flashed a fun and flirty over-the-shoulder look before getting in her car and driving off.

'Dancing really brings out the confidence in a gal,' Brinkley-Cook wrote across a picture from her rehearsal that she posted on her Instagram story late Saturday afternoon.

Around the same time, she also shared a snap of herself with her dance partner on a couch with their airs in the air like wings, along with a female friend.   

Keep in mind, Brinkley-Cook stepped-in to compete on DWTS when her mother Christie Brinkley tripped and broke her arm last week. She had just three days to prepare and learn her Foxtrot to Uptown Girl, which wowed many in the audience and the judges.

From the sounds of her consistent social media posts, it appears Brinkley-Cook is ready to step up their performance up a notch or two.

'Hey Val, you ready to rumba? Meet you under the mirror ball 8pm Monday bro,' she wrote on Instagram on Thursday along with a picture of the two posing during practice.

What makes this all-the-more impressive is that she has never dance before, let alone in front of a live television audience. 

'I didn't want to at first, honestly,' Sailor admitted to People

'I was terrified. It was a very scary thing for me. The whole idea of having to be live on stage, be on TV dancing, that's something I've never done before.'
