Jennifer Lopez says she has "so much love" for rumored boyfriend Drake. The 47-year-old American singer couldn't help but gush about the 30-year-old Canadian rapper Sunday at the 2017 Grammy Awards following reports their romance has "fizzled." "I love Drake. He's so brilliant, talented, amazing," Lopez told Ryan Seacrest during an interview with E! News on the red carpet. "We made a song together," she added of their forthcoming collaboration. "Yes, absolutely, [creative sparks]. We hung out. We have a great time. He's amazing. I have so much love for that boy." Drake was nominated for eight awards at the ceremony, and won Best Rap Song and Best Rap\/Sung Performance for "Hotline Bling." Sources had told "Entertainment Tonight" last week that Lopez's relationship with the rapper had cooled down due to their hectic schedules. "She likes Drake," an insider said. "They're just busy, so it has fizzled." "She's a mom with an insanely busy career. He's touring in Europe," the source elaborated. "Who knows what will happen in the future when they're more able to be in the same place." Lopez and Drake were first linked in December after the rapper attended Lopez's concert in Las Vegas, and shared a kiss at a winter party the same month. People reported at the time that the singer seemed "very happy" to be spending time with Drake. "She has nothing but nice things to say about Drake," a source said. "Drake is very charming. He treats Jen with lots of respect. She seems very smitten." Lopez last released the album A.K.A. in 2014, which includes the singles "I Luh Ya Papi" and "Booty." She shares 8-year-old twin children, daughter Emme and son Max, with ex-husband Marc Anthony.
