Kelly Clarkson belts out her biggest hits in Las Vegas as the toy store spat rolls on

Kelly Clarkson did not let her online fight with a Brooklyn toy shop keep her off the stage. The singer powered through a big show Wednesday night in Las Vegas.

A packed stadium night

Clarkson performed at a corporate event inside Allegiant Stadium and looked stunning doing it. People at the show say she seemed genuinely "thrilled" to be singing for the huge crowd.

She hit the soaring notes of "Stronger (What Doesn't Kill You)" and worked through more of her best-known songs. The set included "Favorite Kind Of High" plus "Breakaway" and "Since U Been Gone."

She reportedly did not bring up the toy store drama at any point during the night.

How the feud started

Clarkson has been trading jabs online with Art of Play, a Brooklyn shop that sells puzzles and curiosities. Last Saturday she stopped in to buy a few things and asked about Molly, a $15,000 mechanical bird hanging on the wall.

She came away feeling brushed off. Clarkson says a staff member acted as though she could not afford the piece and she likened the moment to Julia Roberts' character in "Pretty Woman."

The store's side

The shop answered her posts more than once. In one follow-up the shop explained that the $15,000 price tag actually applied to a near twin of Molly that belongs to Seattle artist Bliss Kolb. It also said it offered Clarkson a different singing bird for about $2,000 before she left.

Journalist Pablo Torre later released silent security video from inside the store. In the clip Clarkson looks around the shop and gestures toward Molly before a tense, emotional talk with the worker.

As for Molly, the bird now carries an eye-popping $15 million asking price.
