The 'Empire State of Mind' singer pulled out all the stops for the event in a glamorous floor-sweeping gown, which featured peek-a-boo cut-out details across the front.
Her stunning crimson number hugged her curves in all the right places, showing off her incredible hourglass figure.
Alicia - who is the co-founder and global ambassador of the charity - kept her jewellery minimal, simply adorning each figure with a dainty silver ring.
The starlet swept her locks into a fierce quiff while sporting feline liner and a nude glossy pout.
Her only accessories? Hubby Swizz and her cutie pie son Egypt, of course!
The adorable three-year-old was grinning from ear-to-ear as he snuggled up with his mum and dad, flinging an arm around both. Awww!
He's clearly inherited his mother's knack for fashion too, looking cool as a cucumber in a varsity jacket and Converse trainers which were both customised with his name.
Your red carpet style gets a thumbs up from us, Egypt!
