George Kittle admitted he couldn’t resist the once-in-a-lifetime opportunity to duet with Taylor Swift.

The San Francisco 49ers star was caught belting out the pop sensation’s 2008 hit ‘Love Story’ with her during a party at Tight End University – a football event he co-hosts with her boyfriend Travis Kelce – last month.

And the tight end revealed what it was really like to not only brush shoulders with the A-List star but to also share a harmony or two.

‘That was a fun one,’ Kittle told NBC Sports’ Matt Maiocco, while competing at celebrity golf tournament the American Century Classic in Lake Tahoe, where Kelce is also participating this week.

‘I was in the process of handing [my wife] Claire and Taylor drinks for the night, and I was like, “I just gotta tell you that ‘Love Story’ … is definitely my favorite Taylor Swift song,”‘ he recalled. ‘And as I was telling her, it came on the speakers, and I was like, “I’m not going to miss this opportunity.” You don’t get to sing “Love Story” with Taylor Swift very often.’

‘It was just an absolute riot and something I’ll probably remember forever,’ the NFL star added. ‘I’ve had a fun offseason.’

Kittle recorded a selfie video of him standing next to Swift as the pair belted out her classic hit from her second studio album, ‘Fearless,’ as the song played at the bar they were visiting.

At one point, Kittle panned the camera around and appeared to show Kelce singing along as well.

Swift’s impromptu duet with Kittle wasn’t her only performance during the weekend in Music City.

The following night, the songstress took to the stage – for the first time since buying back her masters – to deliver a surprise performance of ‘Shake It Off’ at Nashville’s Brooklyn Bowl.

Singers such as Sophia Scott, Graham Barham and Chase Rice were all listed to perform at the venue, where Swift was first spotted enjoying the night in the VIP section.

Jordan Davis also played and welcomed country star Luke Combs onto the stage but Swift’s involvement had been kept a secret – if it was even scheduled at all.

Swift told the crowd ‘we planned that three minutes ago’ shortly before she left the stage to huge cheers.

Just when it seemed like Brown was finishing his set, Swift ignited a frenzy when she walked out for one more song and played an acoustic guitar belonging to Rice.

She dedicated it ‘to our favorite players’ before launching into a rendition of one of her biggest hits and sending the crowd wild.

Tickets had been on sale to the public and some devoted Swifties had made sure they were in the crowd for a possible sighting of the singer with Kelce. It was a gamble that seriously paid off.

Nashville’s Brooklyn Bowl hosts up to 1,200 people while her biggest Eras show was at the Melbourne Cricket Ground in Australia, where 96,000 people went to see her.
