The 19-year-old took the "hard decision" to speak about his sexuality via a video on YouTube, but has claimed that he still 'fancies' girls.
While the Olympic bronze-medallist received a hoard of supportive messages on Twitter, some comments have been rather unsavoury.
Morgan wrote on Twitter: "To all the homophobes out there spewing bigoted bile about Tom Daley, I laugh in your wretched little faces. You're losing, he's winning."
Daley revealed that he met his boyfriend earlier this year.
