Seems like things are heating up between Lewis Hamilton and Rita Ora. The Body On Me singer was spotted at the Abu Dhabi Grand Prix on Sunday.

According to The Sun, the 26-year-old looked downtrodden in the Mercedes' garage from where she saw her rumoured boyfriend relinquish his Formula One crown to teammate Nico Rosberg despite finishing ahead of the latter in the race. Ora was dressed in a short white dress, which she paired with matching thigh-high boots and hat.

While neither has confirmed their relationship status, the two have been spotted together on numerous occasions.

In July, the Mercedes' driver was seen leaving the pop star's house in the early hours. Later, the songstress was spotted with the 31-year-old at a bash he threw with Wimbledon champion Serena William. The same month the two were pictured enjoying their time during a secret holiday.

"Things have been heating up between Rita and Lewis for a while, and now they have taken them up to the next level. They clearly enjoy each other's company and seem closer than ever." a source previously said.

Hamilton previously dated singer Nicole Scherzinger on and off for 7 years before they ended their romance in February 2015. Rita on the other hand has been linked to Calvin Harris, Rob Kardashian and rapper Ricky Hil, who she split from in 2015.

Just days after their split, the former Pussycat Doll member told The Telegraph that she ended the relationship to focus on her career.

"I try not to regret things, because I feel like as long as you put positive energy towards something — and you put your whole self, your true self, towards it — it'll lead you to the next place you're supposed to be," the 38-year-old Scherzinger said.

"I look at this as a great blessing for me to be able to take on this role... but I have made sacrifices. This is very time consuming. I've left LA, left all my friends and my family. It's sacrificing your time in relationships, with loved ones, and my work," she added.
