Nicole looked simply sensational as she sat courtside, anxiously watching her boyfriend do his thing while ringing her hands in anticipation of the result.

Oozing glamour, the stunning star wore a simple white top paired with jeans and added a touch of cool with a leather bomber jacket which coordinated with her gladiator sandals.

While her outfit was relatively simple, Nicole let her make-up do the talking with a dramatic slick of deep red lipstick emphasising her pout and chic sunglasses shielding her eyes.

Her long brunette tresses were worn in voluminous curls which cascaded over her shoulders flawlessly - clearly prepped for a glamorous day.

After the match, Nicole looked dejected as she walked alongside her handsome beau following his unfortunate defeat at the Roland Garros.

The sportsman was no doubt overjoyed to seek comfort in his pop star lady, as they headed out of the match with him sporting a pair of black tracksuit bottoms and a hoodie.

Just one day before the superstar couple put on a cosy display as they enjoyed some pre match snuggles and a low-key trip out of their hotel.

Nicole proved just how comfortable she is with her younger man, as she sported just a baggy grey jumper and loose fitting navy tracksuit bottoms - simple and laid-back attire.

Drowning the dancer's figure for which she has become known, she sported the extremely loose fitting look without a care in the world.

Her box-fresh white trainers matched the white top she sported underneath - a suitably sporty look for her day out with her sportsman beau, who was equally as low-key.

She showed off her youthful complexion by going totally make-up free while her hair was worn in an unkempt style - proving herself to be at total ease.

Grigor meanwhile sported a camouflage hoodie in a plethora of shades of blue, while he wore matching navy tracksuit bottoms to coordinate with Nicole's.

Pulling on a Nike cap, he cut a low-key figure, although his teetering stature made him stand out, particularly when walking alongside his diminutive girlfriend.

Nicole is no doubt a comforting presence for Grigor, who said after his defeat: 'I’ve lost a lot of confidence in myself. It’s not easy to come off losing those kind of matches... What scares me is that I’m really not finding a way and usually I’m pretty good at bouncing back.'

Last month it was claimed that she called time on her relationship with Grigor, yet Nicole's representatives confirmed to MailOnline that reports of the pair’s split are ‘completely false’.

A source reportedly told The Sun: ‘Nicole is at a different stage in life to Grigor. She really likes him but wants to settle down – something he’s not quite ready for.

‘It’s the situation she had with Lewis, which is why the relationship stalled. She’s aware she is not getting any younger and wants kids.’
