The retired quarterback did not specify exactly when this took place, but he played for the San Francisco 49ers between 2011 and 2016.
By the time he left the NFL, Colin was in a relationship with radio host Nessa Diab, with whom he welcomed a baby in 2022.
Diab, 45, revealed in August 2025 that they wed “years ago.”
Swift, for her part, started dating Kelce, 36, in the summer of 2023. The couple got engaged in August 2025 and married this July.
Colin explained in his memoir that his mom’s comments about Swift, 36, affirmed his belief that she is not “capable of seeing who [he] really” is.
He went on to share an instance during which Tessa “convinced” him to ask a classmate to a school dance.Noting that “Lindsay was white,” Colin wrote that their picture from the dance was “promptly plastered … on the wall for all to see” and the same was not done when he took a black classmate named Crystal to homecoming.
“When I got the official portrait from that night, featuring me and Crystal posed up in that classic, airbrushed frame, my mother hid it away in the back of a drawer,” Colin claimed. “In her mind, Crystal was just a phase. Lindsay was the kind of girl I should want.”
Elsewhere in his book, Colin documented his journey to the NFL and, ultimately, out of the league in 2016 after controversy over kneeling during national anthems as a protest against racial injustice and police brutality.
