The princess of glam is back!
Kate, 31, stunning in a Jenny Packham pale gold full-length sequin gown with crystal motif, accompanied husband William for the first Tusk Conservation Awards, part of his African charity.
“As you might have gathered, Catherine and I have recently become proud parents – of a baby who has a voice to match any lion’s roar!” the proud dad, 31, said to applause, asking that guests pardon the couple’s anxiety.
“This is actually our first evening out without him, so please excuse us if you see us nervously casting cheeky glances at our mobile phones to check all is well back home.”
And Kate, who teamed her gown with Jimmy Choo sandals and a diamond bracelet said to have been a wedding gift from her father-in-law, Prince Charles, told a well-wisher that 7½-week-old George “has a mix of both of us.”
The couple said they’d left Prince George at home with his nanny Jessie Webb, 71, who’s recently stepped in to help the young family. She also looked after Princes William and Harry when they were boys.
