Love is in the air! Rihanna jets into London with billionaire beau Hassan Jameel... days after sparking engagement rumours with huge diamond ring

She set tongues-wagging last week after she was spotted with an eye-catching diamond ring on her wedding finger.

And as speculation mounts, Rihanna cut a stylish figure as she jetted into London alongside her beau Hassan Jameel on Monday.

The 29-year-old hitmaker donned a warmth-inducing red, white and navy print coat as she walked through Heathrow Airport with her Saudi Arabian boyfriend.

The Work singer teamed her horse patterned jacket with a pair of skintight leggings which highlighted her slender pins.

Ready to combat the chilly temperatures, she placed a thick black scarf over her neck while she donned a pair of shades while walking through the terminal.

Continuing her casual display, she worked a pair of white trainers with her low-key ensemble and draped a Dior crossbody bag over her shoulder.

Accentuating her flawless complexion, she styled her glossy locks into a sleek top knot. 

Complementing his stylish other half, Hassan appeared ready for the chillier weather as he sported a padded jacket over a thick jumper.

The businessman teamed his look with a pair of grey jeans, matching trainers and a beanie hat following his long-haul flight. 

According to eyewitnesses, the pair took over two hours to come through the terminal.

They had used the exclusive Windsor Suite, which is supposed to enable VIPs to arrive and leave the airport with minimal delay. 

This comes after the Work hitmaker flashed what appeared to be a diamond engagement ring on her wedding finger last week in New York City. 

Rihanna - who has been dating Hassan for about a year - was sporting the large rock as she left Madison Square Garden where she took in Chris Rock's stand-up comedy performance.  

The ring - whihc had not been seen before - appeared to have a large center stone that could have been a champagne diamond which was surrounded by several large white diamonds that created what looked to be a daisy pattern. 

Rihanna and Hassan were last seen together enjoying dinner in September in London

During the outing, the SOS singer did not appear to be with Jameel as she was only seen with a bodyguard - who escorted to her waiting car.  

It could be a piece of costume jewellery or fine jewellery she bought for herself but given how happy she seems with Hassan, it might just be a sign she is ready to wed.

Rihanna and Hassan were last seen together in Boston on Halloween; they were bowling at Lucky Strike Lanes. 

'Rihanna was dressed as Kylo Ren from Star Wars and Hassan was dressed as a penguin. They were all super nice and friendly, ' a source told UsWeekly at the time.

In September, the couple were spotted enjoying dinner in London together, yet exited separably with Rihanna waiting in her car for 30 minutes before he joined her.

Hassan is the deputy president and vice chairman of family business Abdul Latif Jameel – one of the biggest companies in the world. 

And Rihanna is not the first of his famed romances as he was previously linked to Naomi Campbell.

Hassan was previously married to art expert Lina Lazaar after the pair wed at Paris' Opera House in 2012. 

Bright idea: Over the weekend the stunner shared this photo to Instagram plugging her new Fenty Beauty lipstick color.
