the queen of Sheba is a historical character that has been mentioned in religious texts sacred to Jews, Christians, and Muslims. she is considered as a symbol of the seeker of truth and wisdom . I think she is a symbol of Beauty as well . I hope that could help :)

King Sulaiman (from Quran) married Queen of Sheba. She was from Ethiopia or somewhere in Eastern Africa. The King was son of David. Both he and his father are prophets in Islam. King Sulaiman was put in charge of all the djinn in the world and moved something with help of djinn (story in Quran not sure what Surah.)

The Queen of Sheba is from biblical times. She was a powerful and wealthy queen from Ethiopia. If someone says that you are acting like you're the Queen of Sheba they could be saying you are acting like you are high and mighty (like the Queen of Sheba) and better than everyone else.

Hello. It is an idiomatic expression. Meaning for this idiom: a girl who believes she is better than you, not perfect, but better than YOU.
