Cristiano Ronaldo joined girlfriend Georgina Rodriguez for a meal at a posh Paris restaurant on Sunday night.

Ronaldo, 33, was spotted exiting the Cesar restaurant on the Champs-Élysées with the mother of his youngest child, as the star’s legal team continues to challenge the rape claims in the United States.

Rodriguez, who has been in a relationship with Ronaldo since 2016, is standing firmly behind the Juventus striker and the pair enjoyed a romantic evening at the Italian restaurant.

If Ronaldo had hoped to make a quiet exit post-meal however, he will have been left disappointed with a host of onlookers and fans waiting outside.

It comes after Ronaldo shared a rare family photo with his 142 million Instagram followers on Friday, amid the rape allegations made against him.

Former model Kathryn Mayorga has claimed the five-time Ballon d'Or winner raped her in his penthouse suite at the Palms Casino Resort in Las Vegas in 2009.

Ronaldo "vehemently denies all accusations" made against him.

In a statement last week, lawyer Peter S Christiansen declared the documents are "pure invention" and have been fabricated by hackers.

Christiansen says Ronaldo's position continues to be that "what happened in 2009 in Las Vegas was completely consensual."

Ronaldo and Rodriguez stepped out in the French capital just hours after Portugal - whom Ronaldo captained to Euro 2016 success - defeated Scotland 3-1 at Hampden Park.

Ronaldo has been absent from the Seleccao squad since the World Cup in Russia.

He has missed their last four fixtures and will also miss next month's UEFA Nations League matches against Italy and Poland.
