Lena Dunham seems to have taken a liking to Brad Pitt when they co-starred in the Quentin Tarantino film Once Upon A Time In Hollywood.

The two were often seen chatting during down time on the Los Angeles set in 2018.

And on Tuesday evening the 33-year-old Girls star was photographed kissing the movie icon, who has been single since splitting from Angelina Jolie in 2016, in front of other A listers when on the red carpet at the London premiere.

Kiss me! Lena Dunham seems to have taken a liking to Brad Pitt when they co-starred in the Quentin Tarantino film Once Upon A Time In Hollywood; here she is seen planting a kiss on him at the London premiere on Tuesday

Single , but is he ready to mingle? The fox has been single since splitting from Angelina Jolie in 2016

Brad, who was dapper in a dark suit with his blonde/silver hair styled just so, looked taken by surprise as the TV vet went in for the smooch while on the red carpet at the Odeon Luxe Leicester Square.

The two were not alone.

Behind them were Margot Robbie, Leonardo DiCaprio, Quentin Tarantino, Daniella Pick and Costa Ronin.

Leo seemed to glance at the two during their display of affection.

I only have eyes for you, Mr Pitt: Leonardo DiCaprio was not the recipient of her charms as she completely ignored the Titanic stay

Even when standing in line away from Brad, she turned her entire body to get a good look at the Troy star, who has been a pinup since the 1991 when he starred in Thelma & Louise with Geena Davis and Susan Sarandon.

His heartthrob status only grew with A River Runs Through It and Legends Of The Fall; a marriage to Jennifer Aniston made him tabloid fodder and his union with Jolie cemented his mega fame.

Dunham - who dated musician Jack Antonoff from 2012 to 2017 - seemed far from shy with Pitt, making a bee-line for him to plant a kiss on him.

She also could not be missed in her spectacular orange sequined dress with red feathers. Lena added black strappy platform heels for even more glam.

No privacy for these two: The two were not alone. Behind them were Margot Robbie, DiCaprio, Quentin Tarantino, Daniella Pick, Costa Ronin

His scruffy man look: Brad had messy hair and a grey beard with a deep tan

Her glam was just right as her makeup was very flattering and her hairstyle suited her perfectly.

Dunham plays Gypsy in the film, one of the Mansion girls. She is one of the first people Pitt's Cliff Booth meets when he discovers the Manson family.

In October 2018 Lena was seen flashing Pitt her underwear on set.

She was lifting her dress and apparently flashing him as Margaret Qualley stood by in the street.

You can't hide from me! Even when standing in line away from Brad, she turned her entire body to get a good look at the Troy star, who has been a pinup since the 1991 when he starred in Thelma & Louise with Geena Davis and Susan Sarandon

On the move: The star seemed to really want his attention. If they dated, he would have a girlfriend that was 22 years younger than him

Bravo! She also could not be missed in her spectacular orange sequined dress with red feathers. Lena added black strappy heels for even more glam

The movie: Pitt plays the stuntman to Leonardo's movie star in Once Upon A Time In Hollywood

When Dunham appeared on Jimmy Kimmel Live! she was grilled over the incident.

'Was this part of the movie?' Kimmel asked.

Shaking her head, Dunham replied, 'Certainly no. That was between takes, [with] him trying to sort of chill and brush up on his lines. It made sense in the moment. We were talking about kewpie dolls.

An incredible woman: Meanwhile, Brad's ex Jolie wrote a riveting essay for Time on Wednesday about the US/Mexico border crisis; here she is seen with Brad in 2009

'Do you guys know what a kewpie doll is? It's like an illustrated character of the 1920s. Someone asked, "What's a kewpie doll?" And I said, "Well, I can show you. I've got one right here on my side"...If you've got it illustrated on your body, who are you not to show this?

'My publicist actually asked me directly not to do it again on this show. She said, "No matter what comes up out there..." I want to do it really bad right now!'

Meanwhile, Brad's ex Jolie wrote a riveting essay for Time on Wednesday about the US/Mexico border crisis.

The Oscar-winning actress said, 'We all want our borders to be secure and our laws to be upheld, but it is not true that we face a choice between security and our humanity: between sealing our country off and turning our back to the world on the one hand, or having open borders on the other. The best way of protecting our security is by upholding our values and addressing the roots of this crisis. We can be fearless, generous and open-minded in seeking solutions.'
