Katherine Jenkins Rocks LBD To Celebrate OBE With Family (But Arrives Minus New Man Andrew Levitas)

Katherine Jenkins has just received her OBE for services to music and charity, and had more than one reason to beam as she posed with new boyfriend, Professor Andrew Levitas at Buckingham Palace.

But it seems she's not ready to introduce him to the parents just yet, as she enjoyed a low-key family celebration later at the The Ivy in London, but arrived minus her man. The pair reportedly met in LA in October, so we guess it is a little early for intros.

For the family meal, Katherine was looking elegant, switching up the colourful Preen dress she'd worn in the daytime for an on-trend off-the-shoulder black number. She accessorised with a bright, studded cobalt-blue clutch, peep-toe heels and a pair of diamond drops. Tres chic.
