Travis Kelce poses with Lance Bass without Taylor Swift while attending Justin Timberlake’s concert solo… as couple are ‘nesting’ at singer’s $25 million Beverly Hills mansion

Travis Kelce excitedly posed with Lance Bass backstage at Justin Timberlake‘s concert in Los Angeles on Wednesday – but his girlfriend Taylor Swift was nowhere to be found.

The NFL star, 34 – who is ‘nesting’ at the singer’s $25 million Beverly Hills mansion amidst downtime in their careers – could be seen flashing a cheerful smile as Bass draped his arm over the football player’s shoulders.

The NYSNC member, 44, uploaded the image to his Instagram stories and typed, ‘Karma is the guy on the Chiefs.’

Swift notably sang those lyrics when she changed a portion of the track, Karma, during her Eras Tour stop in Buenos Aires to reference her budding romance with the Kansas City Chiefs tight end.

Lance additionally tagged Kelce in the photo while also adding the hashtag towards the bottom that read, ‘#STILLNOTTAYLORSWIFT’

Travis was stylishly casual as he stopped by the concert while sporting a dark gray sweater that had a V-neck cut on the front.

He also slipped into a pair of tan-colored, baggy trousers while adding a necklace, as well as a beaded bracelet and watch on each of his wrists.

Bass was dressed for the special night by wearing a black suit as well as a plain, black shirt underneath.

During the free concert, Timberlake – who dropped his new album Everything I Thought It Was on Friday – notably brought out his NSYNC bandmates onto the stage – including Lance, JC Chasez, Joey Fatone and Chris Kirkpatrick.

Their performance together on Wednesday was the group’s first in over 10 years – with the last time the boy band took to the stage occurring back in 2013 at the Video Music Awards.

Other celebrities were in attendance during the big night – including Chrissy Teigen and John Legend who shared snippets from the concert.

Lance is also a big fan of the Blank Space hitmaker and last year in October while attending a NFL game to watch the San Diego Chargers take on the Denver Broncos – he humorously held up a sign that read: ‘Not Taylor Swift.’

Kelce was spotted leaving the venue following the lighthearted festivities – but Taylor Swift did not join her beau for the outing.

The couple are currently ‘nesting’ as they enjoy a pause in their careers at her $25 million Beverly Hills mansion.

The Grammy winner – who has no commitments and plans to ‘play house’ with the NFL player – is set to kick off the European trek of her sold-out Eras Tour two months later in May.

She recently concluded her tour stops in Australia and Singapore, with the Kansas City Chiefs star also attending to cheer on Swift.

A source told Us Weekly in an article published on Thursday that the lovebirds are ‘nesting’ and ‘focused on rest and recuperation and relaxing at home and having low-key and chill time together.’

‘They are enjoying movie nights in her home theater, catching up on films and shows they’ve missed.’

‘They can finally rest and intend on spending quality time together and with friends and family,’ the insider continued, adding that Swift likes to throw ‘small, intimate gatherings’ for those close to her.

The couple – who went public with their budding romance last fall – have been trying to arrange their schedules so ‘they can see each other as much as possible. They don’t want to spend too much time apart.’

The source also revealed that, ‘Toward the end of the month they’re still talking about going on a private vacation where no one can find them before her new album drops.’

Swift’s forthcoming album titled, The Tortured Poets Department – which she initially announced at the 66th Grammy Awards in February – is slated to become available next month on April 19.
