Sanita (The Runaway Bride)
From Tardis Wiki, the free Doctor Who reference
Sanita was a guest at Donna Noble's first wedding, in which Donna disappeared into a cloud of Huon particles. She was also present later on at the wedding reception.
When a Roboform Christmas tree attacked the party, Donna and Sanita both checked in on two children, Michael and Connie, to make sure they were alright. Donna then asked Sanita vaguely to "do something useful" for the other people in shock from the incident. (TV: The Runaway Bride)
