The Spice Girl was seen looking far from her usual sexy and dressed up image on Tuesday (13 August), as she exited her hotel in a pair of patterned leggings, some chunky wedge trainers and a black hoody, and then hopped into a waiting car.
She also appeared to have wiped off the day's make-up and shielded her face with her hood and a pair of large designer sunglasses.
Clutching onto her mum's hand, six-year-old Angel looked adorable in a pink tutu and matching top, which she teamed with a black crochet hat and some sparkly trainers.
The youngster - whose father is comedian Eddie Murphy - had flown out to New York to watch Mel in action on the America's Got Talent judging panel.
Mel, 38, posted a sweet snap of Angel on board their private plane on Monday (12 August) and revealed that the tiny tot would be jetting to the Big Apple, since Mel's eldest daughter Phoenix had got to come along the week before.
She wrote: "Phoenix got to go last week now angel this week #AGT"
The pop star - who is married to film producer Stephen Belafonte - also uploaded a cute picture of Angel sat on her lap while she was sat in her judging chair.
The photo shows Mel's fabulous look for the day of filming, hours prior to her stepping out in her laid-back ensemble.
She wore a short metallic number with a chunky chain necklace and smoky eye make-up, while styling her hair in ultra glam curls.
But clearly the over the top outfit and heavy make-up was a little too much for Mel, since she was quick to ditch the frills and her fancy fashion for something much more comfy later on.
She's definitely a girl after our own hearts!
