Sapphire Shores

Sapphire Shores is an earth pony who is a famous popstar in Canterlot.

Personality
Sapphire speaks with a loud and theatrical voice, and frequently inserts musical intonations into her sentences. She appears to be a parody of the self-promoting star who is always "on." Despite her fame and over-the-top mannerisms, she seems to be quite friendly and approachable toward Rarity: she visits Rarity's shop personally and asks to be called by her first name, which absolutely thrills Rarity.

History
She appears in the introduction of A Dog and Pony Show, walking into Rarity's shop after hearing about her fashion design. Rarity is awe-struck when she sees Sapphire, and addresses her as "The Pony of Pop." She is enthralled by Rarity's newly-made diamond garment and wants to buy it for her tour, along with five more costumes in gems of different sorts, unaware that Rarity used all of her gems to make the garment. The episode follows Rarity's search for gems for Sapphire's costumes.

Trivia

 * Sapphire Shores is named after a Generation 3 earth pony, however her design, coat color and cutie mark are very different from the original. Her G3 release has a pink coat and a seashell cutie mark while her Friendship is Magic version has a pale olive coat and no visible cutie mark due to a design oversight.
 * Sapphire Shores' tour is called Zigfilly Follies, referencing the elaborate Broadway production Ziegfeld Follies.
 * Many fans say that Sapphire Shores is similar to Janet Jackson, Queen Latifah and Beyoncé.
