There&#8217;s little doubt Jennifer Lopez knows how to put on a show.
And for the American Idol finale, Jennifer Lopez dazzled the crowd with a cover of Rihanna&#8217;s Diamonds and a barely-there glitter gown.
&nbsp;
The 45-year-old&#8217;s garment flirted with the imagination as she performed the pop track with co-judges Keith Urban, 47, and Harry Connick Jr., 47, on Wednesday.

Putting on a show! Jennifer Lopez dazzled the crowd at the American Idol finale with a cover of Rihanna&#8217;s song Diamonds
&nbsp;
Jennifer assumed control of a glittering microphone as Keith strummed his guitar and Harry sat behind a piano.
While her co-stars appeared to coordinate with their matching black attire, Jennifer upped the glam factor with her sparkling dress and large hoop earrings.
Her hair fell down in a straight and glossy &#8216;do, and her radiant face glowed with heaps of smoky eye shadow.

Very pleasing: The stars got the glittering crowd to their feet with their performance
After Jennifer&#8217;s soulful take on the pop song, the atmosphere livened up to the tune of Bruno Mars&#8217; song Locked Out Of Heaven.
The Boy Next Door actress joined into the song after Keith belted out the initial lyrics.
Jennifer and Keith&#8217;s talent continued to shine throughout the night.
While Keith performed Even The Stars Fall For You, Jennifer at one point traded in her gown for a short black mini to sing Back It Up with Pitt Bull and Prince Roy.
A host of scantily clad back-up dancers paraded beside Prince Roy as he sang his brand new single.
Pitt Bull joined in his signature uniform of beige slacks, a handsome blazer, and sunglasses.

Showing what she&#8217;s got! The singers grooved to the tune of the music as a bevy of back-up dancers frolicked beside them
And after being lost for words to describe his feelings at winning, Nick had to halt his performance of his debut single to instead run into the crowd and hug and kiss his family.
The Adam Levine-lookalike from Guildford, Connecticut, had perhaps gone into the final as favorite, at least for the judges who had been harsher with their comments aimed at Clark during the season.
But in front of a live audience that including Hollywood superstar Nicole Kidman and former Idol judge Steven, Nick seemed clearly overwhelmed as his name was read out as the winner.After being swarmed by the other contestants from season 14, host Ryan Seacrest asked for his reaction and Nick admitted: &#8216;I can&#8217;t even think right now.&#8217;
