Mandy Teefey - who divorced Selena`s father, Ricardo Gomez, when the `Love You Like A Love Song` singer was five-years-old and married Brian Teefey in 2006 - is expecting her second child later this year. Selena announced the news on her Twitter page by sharing a picture of her and her pregnant mother and writing a sweet Mother`s Day (12.05.13) message. She wrote: "Hope all the amazing moms had a great day! I have the best momma in the world :)) I love you so much! (sic)." Meanwhile, Selena recently revealed her rider for her upcoming `Stars Dance` world tour includes pickles and incense. She said: "[I have] incense, pickles always. I don`t know. I actually have a boring rider." "I`ll be honest…ramen. That`s what I have. I`m more about food and apparently incense." Selena also shared her inspiration behind the tour name. She said: "It`s actually a track on the record and I just felt it was a perfect name for every track that`s on the album. They have their own individual stamp and style to it, but with this tour and wanting to incorporate more of the performing aspect, I thought it was the perfect way for kicking it off."
