Lady Gaga responds to Bradley Cooper romance rumours

Forget who won what at the Oscars - all anyone has been talking about since the awards is Lady Gaga and Bradley Cooper and their show-stopping, lovey-dovey duet.

But don't get too excited about a real-life romance between the A Star Is Born actors, as Gaga has dismissed the rumours.

In an interview with US TV host Jimmy Kimmel following her Oscar win (she picked up the award for best song for Shallow), the singer said that just like the film, it was a performance.

So that's it. Just a very convincing, intense, deeply romantic - did we mention intense? - performance. Which you would hope they are good for, seeing as they were both nominated for acting Oscars too.

Addressing the rumours that swirled on Twitter following the duet, which saw Gaga staring into Cooper's eyes across a piano before he joined her at her seat, the singer also described social media as "the toilet of the internet".

In an appearance on Jimmy Kimmel Live on Wednesday, the host asked the 32-year-old about the performance.

Gaga rolled her eyes and said: "First of all, social media quite frankly is the toilet of the internet and what it has done to pop culture is abysmal.

"And people saw love, and guess what, that's what we wanted you to see. This is a love song, the movie is a love story."

Shallow, which was co-written by Mark Ronson, has scooped up Grammy and Golden Globe awards, as well as the Oscar.

Gaga said she was comfortable with Cooper, 44, directing the performance, as he did with the film.

She said: "From a performance perspective it was so important to both of us that we were connected the entire time."

Gaga also pointed out her past performances with legendary singer Tony Bennett, who is 92.

"I mean, look, I've had my arm around Tony Bennett for three years touring the world," she said. "When you're singing love songs, that's what you want people to feel."

Kimmel jokingly asked her if she was having an affair with Bennett.

Gaga, holding up the Oscar she won for best original song, replied: "No, I'm an artist and I guess we did a good job and, told ya."

She added: "I don't feel like I won, I feel like we won."

Meanwhile, following its success, A Star Is Born is to be re-released in the US with almost 12 additional minutes of footage, including extended versions of some songs and new scenes between Gaga and Cooper's characters, Ally and Jackson.

The film explores the love story between ageing alcoholic rock star Jackson and Ally, the young singer whose career he champions.
