Selena Gomez and Justin Bieber appeared to be as happy as ever when they attended a church service together last week, but has the "Wolves" singer already grown tired of her boyfriend?

According to a new report, the 25-year-old recently shared a social media post with her fans in which she said that she could use some time to herself.

“I need some alone time,” she captioned a clip on Instagram, according to an article shared by Hollywood Life on Dec. 4.

Gomez has been spending time in London in recent days after attending the Billboard Women in Music event days ago. As fans will recall, Gomez opened up about her friend Francia Raisa during the event, revealing that she was likely still alive due to Raisa's decision to donate a kidney to her.

In September, Gomez revealed that Raisa donated her kidney to her and labeled her as her "sister." She also said that she will eventually tell fans more about her kidney transplant.

Gomez and Bieber have been spending time together since initially reuniting in October after over a year apart. Since then, they have been photographed enjoying each other's company in Los Angeles.

Although Gomez and Bieber have been spending a lot of time on the west coast, the newly reconciled couple did not spend the holidays together. Instead, Gomez returned home to her family in Texas as Bieber visited Canada and was spotted spending time at an ice rink.

Gomez and Bieber reunited around the same time that Gomez split from The Weeknd following 10 months of dating. In January, Gomez went public with The Weeknd after enjoying a dinner date in Santa Monica.

Earlier this month, after an on-and-off relationship that was plagued by drama for years, a source claimed Gomez was quite impressed with Bieber's new demeanor.

“Justin has been very open about his feelings towards her and she appreciates and values his candidness and willingness to be vulnerable with her now more than he had during their first relationship stint,” a source close to the couple told Hollywood Life. “Selena is enjoying the refined and mature Justin and she is taking everything a step at a time so not to ruin the great vibes and energy they share together.”

Gomez and Bieber first began dating back in 2010 and continued to be on-and-off in the years that followed.
