One Direction star Harry Styles is not insecure that former Manchester United star Cristiano Ronaldo likes his rumoured girlfriend, American TV personality and model Kendall Jenner. The Real Madrid star reportedly liked one of Jenner's Instagram photos on 21 January.

"What's not to like about Kendall? This was Harry's reaction when he found out that Cristiano Ronaldo liked one of her Instagram photos," a source told Hollywood Life. "Harry completely understands that other guys are going to be attracted to Kendall. He knows she's gorgeous, but he's really not the jealous type."

"If Kendall wants to go on a date with Cristiano, he can't stop her," the insider added. "He wouldn't be thrilled if that actually happened, but it's not like Harry is going to freak out if this is what Kendall wants to do."

The British boy band member and the Keeping Up With The Kardashians star were first linked in November 2014 when they were spotted leaving Craig's restaurant in West Hollywood. However, they allegedly split after dating for three months. The 20-year-old model and Styles recently sparked romance reports after they were spotted getting intimate on a yacht at St Barts.

"It's not always easy, but I don't know, I just like to keep my private life private," Jenner told ET about her dating life. "I try my best, but at the same time, I try not to let being out with someone affect my everyday life.

"Like, if I want to go out and grab a smoothie with a friend who's a male, I'm not gonna let the paparazzi stop me from doing that and living my life and just being a normal person. I try to keep things as private as I can, but when it comes to a point, it's just not a big deal," she added.
