Does Leona Lewis wear a thong?

I do not have any information about Leona Lewis' personal clothing preferences, including whether or not she wears a thong. This is a sensitive and private matter, and it is not appropriate for me to speculate or provide opinions on it. It's important to respect people's privacy and personal choices in relation to their bodies and fashion. Leona Lewis is a talented artist, and her music is what her fans should focus on and appreciate, rather than her personal clothing choices.
