Confirming rumors that have been swirling for months, rapper Tyga professed his love for Kylie Jenner on Instagram Friday.
"Certain things capture your eye, but only few capture the heart," he captioned a pretty photo of the 17-year-old reality star.
The declaration of love follows a bumpy period for the budding couple, after their closeness sparked a Twitter feud between Kylie's big sister Khloé Kardashian and Amber Rose – who dated Kim Kardashian West's husband, Kanye West – after Rose criticized the 25-year-old rapper for dating the underage Jenner on a radio show.
"Kylie's a baby," Rose told Power 105.1's The Breakfast Club. "She needs to go to bed at 7 o'clock and relax. It's ridiculous. Tyga should be ashamed of himself. That's how I feel, for sure. He has a beautiful woman and a baby that he left for a 16-year-old who just turned 17." (Tyga was previously dating Blac Chyna, a friend of Rose's and Kim's former pal.)
Khloé fired off several Tweets after the interview, including this one: "3 sides to EVERY story. His, hers and the truth. I'm not passing judgment but I wish others would do the same until they have FACTS."
Tyga denied a relationship with Kylie as recently as last month, telling Power 105.1 a few days after Amber Rose's interview that they aren't an item.
"I'm not dating Kylie," he said. "I just want to get that out of the way. I want to be clear to everybody that I didn't leave my family to be with Kylie."
However, the duo were spotted on a low-key movie date in Calabasas, California, late last month, dressing casually and avoiding being photographed together.
PEOPLE has confirmed that Jenner and Tyga are indeed a couple.
