Selena Gomez is having the best week ever. The singer announced the release date and title for her upcoming album — her first with new material since 2013's Stars Dance — and is celebrating her 23rd birthday. Selena shared a sweet moment on her Instagram account of a chocolate brownie and vanilla ice cream with a birthday candle and a wish written in fudge on the plate, saying: "I am the luckiest, happiest girl today. Thank you guys so much for all the bday wishes!! I love growing up with YOU." Her famous squad took to social media to congratulate her with Taylor Swift sharing four fun pictures of the pair through the past seven years and touchingly saying: "I love you so much, always."
