The expectant mum looked fit to burst as she glowed on the red carpet in a navy A.L.C dress teamed with a Louis Vuitton bag and shoes.

However, despite looking blooming marvelous, Lily admitted she thought she had 'fat arms'.

She wrote on Twitter: "I know I have fat arms, but dumbbells are for glum belles."
