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 34-year-old NFL star – who is ‘nesting’ at the singer’s $25 million Beverly Hills mansion amid their career downtime – could be seen flashing a cheerful smile as Bass draped his arm over the footballer’s shoulders.

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

Swift notably sang those lyrics when she changed part 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 also tagged Kelce in the photo while also adding the hashtag at the bottom that read “#STILLNOTTAYLORSWIFT”

Travis was stylishly casual as he dropped by the gig wearing a dark gray V-neck sweater.

He also slipped into a pair of tan baggy trousers as he added a necklace, as well as a pearl bracelet and a watch on each of his wrists.

Bass was dressed for the special night wearing a black suit with 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 on stage – including Lance, JC Chasez, Joey Fatone and Chris Kirkpatrick.

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

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

Lance is also a big fan of the Blank Space hitmaker and last year in October while attending an 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 seen leaving the venue after the merry festivities – but Taylor Swift didn’t bring her beau along for the outing.

The couple are currently ‘nesting’ while enjoying a break from 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 on her sold-out Eras Tour two months later in May.

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

A source said Us Weekly in an article published on Thursday that the lovebirds were ‘incubating nests’ and ‘focused on rest and recreation and relaxing at home and having relaxed and leisurely time together.’

“They enjoy movie nights at her home theater and catch up on movies and shows they’ve missed.”

“They can finally rest and intend to spend quality time together and with friends and family,” the insider continued, adding that Swift likes to hold “small, intimate gatherings” for those close to her.

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

The source also revealed that “At the end of the month, they’re still talking about going on a private vacation where no one can find them until her new album comes out.”

Swift’s upcoming album, titled The Tortured Poets Department – which she originally announced at the 66th Grammy Awards in February – is expected to be available next month on April 19.

Earlier this week, a separate source also gave DailyMail.com an insight into the couple’s plans as they fully embrace two months of downtime together.

‘It’s the first time the two have had no commitments and they’re both really looking forward to being a normal couple and playing house.’

“She’s looking forward to sleeping in and cooking dinners at home,” the insider added.

‘They both want their relationship to be as normal as possible and it works because they’re both very aware of their fame but don’t let it get to their heads either.’

Along with her Beverly Hills mansion, Taylor also lives in NYC, while Kelce has a home in Kansas City, Missouri.

‘They will split their time between his house and NYC. Taylor is off Eras until May, but that doesn’t mean she’s completely gone,” referring to the star, who is preparing for her upcoming album’s release.

‘She’s working on her push for everything Tortured Poets in April and Travis is going to be there all the way.’

Despite not making any major commitments during the short break in each of their schedules, Swift and Kelce have been keeping busy on the West Coast.

Over the weekend on Sunday, the lovebirds attended Madonna’s Oscar after-party in the Hollywood Hills, per British Vogue.

But despite attending the star-studded bash, both Taylor and Travis were notably no-shows at the 96th annual Academy Awards.

Kelce also appeared in a photo taken at another after-party on Sunday — hosted by Beyonce and husband Jay-Z.

In the snap, he flashed a cheerful smile as he held an Oscar next to winner Cord Jefferson as well as media personality Tommy Alter.

During the month of February, Taylor resumed her Eras Tour dates in Tokyo as well as Australia.

Kelce supported his girlfriend in Australia and also accompanied her to her concerts in Singapore earlier this month – which ended on March 9.

The NFL player recently opened up about the ‘amazing’ trip in an episode of him New podcast for heights with brother Jason Kelce – such as visiting a greenhouse in Singapore.

While Taylor and Travis are currently enjoying their ‘nesting’ phase, a separate previously shared Us Weekly earlier this month that the couple has no intention of getting married anytime soon.
