Ariana Grande is embarrassed by Big Sean's romantic gestures. The 'Break Free' hitmaker admitted she was left red face during one of the rapper's public displays of affection after he stood up on his chair during a date and belted out Steve Wonder's classic 'Isn't She Lovely' to her. The singer shared a black and white photo of the couple enjoying their evening out together on her Instagram account. She captioned the photo: "fyi he stood up on his chair & started singing Stevie Wonder at the top of his lungs after this photo was taken and i ran to the bathroom and hid (not actually) (sic)." The 'Beware' hitmaker has also been creating little videos of himself singing to send to the 21-year-old popstar so she doesn't feel too upset when he works away. A source shared: "A few days ago, he made a little video of him singing to her in an elevator. She loves that kind of thing. She just wants to know that even when they aren't together he's thinking of her."
