Veena Brady

Veena Brady was one of Donna Noble's friends.

Donna Noble lied to her mother that she was going to stay at Veena's house for a week, when she was actually on her way to travel in time and space with the Tenth Doctor. (TV: Partners in Crime)

Sylvia Noble later phoned Veena to confirm this, but she hadn't seen 'hide nor hair' of Donna. (TV: The Sontaran Stratagem)

After the Earth was transported to the Medusa Cascade and back, Veena texted Donna about the 'planets in the sky'. However, Donna had no memory of the crisis due to her memories of her travels with the Doctor being erased.(TV:Journey's End)

Alternate timeline
In a universe in which Donna turned right instead of left, Veena praised Jival Chowdry when he promoted Donna Noble and she was buying all the drinks. Veena was present when the Webstar appeared. She mistook the ship for a Christmas decoration and was chided by Mooky. (TV: Turn Left)
