MARKING SOVEREIGNTY: Travis Kelce calls Taylor Swift his “EARLY WIFE” at a special gala.

Taylor Swift and Travis Kelce made a striking appearance at Patrick and Brittany Mahomes’ charity auction event, where the Kansas City Chiefs tight end referred to the pop singer as his ‘significant other.’

‘I think, um, I was just talking to my significant other,’ Kelce said, whetting the audience’s appetite for a highly coveted auction item: tickets to her Eras Tour.

‘We might have one other auction item that wasn’t on the docket.’

Swift and Kelce were on hand as guests of Mahomes and his wife, Brittany, who was ripped by one insider for allegedly putting on a front with the pop star.

‘She has too many red flags and people are starting to see through her fake and bitchy persona,’ one inside source told DailyMail.com. ‘She is an opportunist who is clearly not a girl’s girl.’
