The former Spice Girl is a judge on America's Got Talent as well as over here on X Factor which means she's been racking up the airmiles jetting between the US and UK for both jobs.
On Wednesday night, she was lighting up the red carpet in Manhattan attending the latest America's Got Talent taping party at Radio City Music Hall.
Mel turned heads in a backless floor-length black gown with sheer detailing across the front and glittering sequined sleeves. She was also flaunting a super long and super glossy ponytail.
Let's hope Mel pulls out all the glam stops over here when the X Factor live shows kick off, right?!
The following morning, the sparkly dress had been packed away and Mel was pictured out and about in a comfy tracksuit and baseball hat.
Mel was seen leaving a New York City hotel in grey jogging bottoms emblazoned with skull designs and a matching grey zipped hoodie. She kept her hair hidden under a hat.
X Factor kicked off its 11th series in the UK last weekend but at the minute we're still on the pre-recorded audition sessions. The judges won't be needed inthe UK until the live shows start later this series.
Mel is judging on X Factor alongside Cheryl Fernandez-Versini, Simon Cowell and Louis Walsh.
