Even though Taylor Kinney and Lady Gaga have called off their engagement, they're still incredibly close. On Monday, the singer posted a picture of her mom and ex supporting her charity, Born This Way Foundation. "At 30 Rockefeller center my charity the @btwfoundation also offers a place to send kind letters to people," she captioned the snap of them standing in front of an orange mailbox. "@taylorkinney111 and my mom sent letters filled with kind words to soldiers fighting overseas. #ShareKindness" This isn't the first time Gaga has mentioned Taylor since their breakup. Aside from giving an emotional interview about love, she pretty much confirmed that "Perfect Illusion" is about her ex back in October. Can these two please get back together already?
