Grammy winner Taylor Swift was spotted at Kansas City Chiefs tight end Travis Kelce's new $6 million estate after spending time with quarterback Patrick Mahomes and his wife Brittany at their luxurious Kansas City mansion.

According to a source cited by the Daily Mail, Taylor and Travis arrived separately at the Mahomes' residence on Tuesday morning. Taylor, accompanied by her security detail, arrived in a car while Travis drove his Rolls-Royce Ghost. The couple reportedly spent several hours with Patrick and Brittany at their Cass County residence, which features a full-length football field in the backyard.

However, after their visit, Taylor apparently headed to Travis' new estate sans her boyfriend. The NFL star, instead, went to his former house in the Briarcliff West neighborhood, where he lived before his relationship with Taylor started.

Travis had purchased his new 16,000-square-foot home on October 17, seeking privacy in a gated community due to the attention his high-profile relationship with Taylor has garnered, as per TMZ reports.

Life & Style magazine previously reported that Taylor would be staying at Travis' new home for a few weeks during her two-month break from her record-breaking Eras tour. The insider claimed that Taylor and Travis were "playing house," using this time to see how their compatibility holds up with living together.

An insider source revealed that living together was the ultimate test for their relationship, but Taylor and Travis felt surprisingly seamless in their cohabitation. The chemistry between them has been effortless and they are not concerned about any potential clashes.

Scott Swift, Taylor's father, has reportedly given his blessing to their relationship and is supportive of taking it to the next level. Another insider stated that Scott gets along well with Travis and loves seeing Taylor happy.

Their relationship has been moving so quickly that there are already talks of an engagement. "They have already been talking marriage," the insider disclosed, adding that friends believe they may be engaged by Christmas.

Overall, Taylor Swift's visit to Travis Kelce's new $6 million estate signals the progression of their relationship and their mutual desire to spend quality time together.
