Selena Gomez's Mom Disappointed About Justin Bieber Reunion Mandy Teefey is "not happy" about her daughter's renewed relationship with the singer. The two reportedly rekindled their relationship last year after Gomez underwent a secret kidney transplant during the summer. The website GossipCop said while the mom disagrees with Gomez's choices she is happy her daughter is healthy. "She is 25 years old and knows what is at stake with her health. I do not control her the way it has been portrayed. Selena is an adult and can make her own choices." GossipCop quoted Teefey
