Kelly Rowland's given her verdict on Beyoncé's return to the stage, declaring the gigs in Atlantic City "incredible".

The new mum is back performing just four months after the arrival of her first child with husband Jay-Z, Blue Ivy.

"I watched the show two nights in a row, she was incredible. I'm so proud of her," said ex-Destiny's Child bandmate Kelly.

"It's about taking care of your baby, taking care of your body and it seems like that's what she's done, she looked incredible."

Beyoncé was back in her stage outfits for the concerts, and back dancing with her troupe.

Kelly said: "It lasted two hours, jumping, splitting, doing craziness on the stage, she looks incredible, I'm very proud of her."
