Shakira, Hamilton's relationship thickens as they pose with his arm around her

 F1 star Lewis Hamilton posed up for a photo with his arm wrapped around Shakira as the duo was pictured having cocktails Sunday night.

The Colombian singer was spotted cheering on the Mercedes driver at the Spanish Grand Prix, amid rumours they are dating.

Shakira dramatically returned to Barcelona for the first time since she left to start a new life in Miami.

The pop star was seen watching the race at the Circuit de Barcelona-Catalunya, as Hamilton scooped second place following Max Verstappen.

Wearing a patterned shirt, neon pink sunglasses and a white skirt, Shakira was beaming as she watched her pal on the track.

The pair headed out for dinner later with singer Mustafa sharing snaps of the group on Instagram.

He simply wrote in the caption: "May God protect the engineers."

It comes as rumours about a romance between the duo have been sparked after they were spotted on several outings.

The singer was spotted on a boat day with Hamilton and his pals in Miami after he picked her up from the back of her £12million beach mansion late last month.

He made sure Shakira didn't have too far to walk as she trotted down her private dock for the day out on the open-top cruiser.

The Mercedes driver, 38, quickly climbed out of the boat to lend the newly single mum a hand as she joined the group onboard.

Lewis later ensured she made it home safe as he dropped her back off at her plush new pad, where she counts the likes of Jennifer Lopez, Ricky Martin and Matt Damon as her neighbours.
