The woman who just may walk in Kate Middleton’s shoes, Prince Harry’s girlfriend, Chelsy Davy, was spotted at Matthew Morrison’s (Mr. Schue) show in London this week, having a total blast, Us reported.

A source told the mag she was especially excited during Matt’s cover of the NSYNC song, "This I Promise You," which he sang with NSYNC alum JC Chasez.

After the show, the blonde Brit partied it up with Matty Fresh. They were joined by family and friends, including Princess Beatrice's boyfriend David Clark — but it was nothing of Lindsay  Lohan proportions. Chelsy may have been out without her royal boo, but there was absolutely “no flirting with guys,” said the source.
