Katniss can really sing! Jennifer Lawrence belts out Cher's Believe during appearance on Conan with The Hunger Games co-stars

Jennifer Lawrence belted out Cher's Believe after downplaying her singing abilities on Thursday on the Conan show.

The 24-year-old actress and her co-stars Josh Hutcherson and Liam Hemsworth from The Hunger Games franchise appeared together on the TBS chat show that was taped near the San Diego Comic-Con gathering.

Chat show host Conan O'Brien earlier in the day moderated a Comic-Con panel with the stars as they promoted The Hunger Games: Mockingjay - Part 2.

Conan asked Jennifer about singing the ballad The Hanging Tree in the last film that reached number 12 on the Billboard Hot 100 chart.

'First of all, if I had gone [fart noise made with flapping arm] ''Hunger Games'', it would have reached number one,' she claimed.

The Oscar-winning actress then revealed that singing in front of people was her biggest fear.

Liam, 25, chimed in that Jennifer 'likes to sing on occasion.'

Jennifer admitted she liked singing Cher and after a quick countdown by 22-year-old Josh she burst into the 1998 song Believe.

'I can feel something inside me say, I really don't think you're strong enough,' Jennifer crooned before throwing her arms out for a big finish.

Steal Jennifer's style in a little black dress by Giamba

Our love for Jennifer Lawrence knows no bounds.

The Oscar winning actress is so down to earth and funny despite her talent and ridiculously pretty face that it's hard not to fall in love with her. And when it comes to her style we're obsessed.

Off duty she's all baggy jeans and wedge mules with a spot of Isabel Marant and The Row but on the red carpet she's forward looking glamour all the way. Usually seen in Christian Dior, last night for an appearance on the Conan O'Brien show she rocked a particularly pretty dress by Giamba.

If this name is new to you then let us expand. It's the diffusion line of Giambattista Valli, one of Amal Clooney's favorite designers. His creations are fanciful, feminine and romantic and this little black number, with its plunging neckline and floral applique, is to die for.

It's from the Giamba Resort 2016 collection so isn't available to buy just yet so until then recreate the look with one of the dresses in our edit below. Or shop the current line at Luisaviaroma.com (right).
