One Direction members met the Duchess of Cambridge here and gave her their best as a mother to be for the second time.
Harry Styles, Louis Tomlinson, Zayn Malik, Niall Horan and Liam Payne met Middleton at the Royal Variety performance here Thursday.
Styles said that he was shocked Middleton, who already has a 15-month-old son George with her husband Prince William, "didn't look bumpy" at 16 weeks pregnant, reports femalefirst.co.uk.
"I said congratulations on the bump. (Though) she didn't look bumpy," he said.
