Melbourne - Eugenie Bouchard said she was happy to receive a tweet from her favourite popstar, fellow Canadian Justin Bieber, ahead of her semi-final against Li Na.
"I was excited," smiled the teenager.
Bieber's message, "Good luck Genie!" was re-tweeted thousands of times.
It followed an on-court interview when Bouchard answered "Justin Bieber" when she was asked who she would date if she had the choice.
Australian broadcaster Channel 7 rejected a comment in Canadian media that the question was sexist.
"We try to give an insight into personalities," a statement from the broadcaster said, according to the Herald Sun.
Unfortunately for Bouchard she lost her semi-final match 6-2, 6-4 to Na.
