Britney Spears reunites with son Jayden, 18, as she celebrates the 'best Christmas'

Britney Spears reunited with her youngest son, Jayden, during the Christmas holiday - and the star shared an Instagram video on Wednesday to commemorate the big moment. 

The Baby One More Time songstress, 43 - who recently returned from a lengthy getaway to Mexico for her birthday - filmed herself with the 18-year-old as they spent time together. 

The star notably shares Jayden as well as Sean Preston, 19, with ex-husband Kevin Federline. Her sons moved to Hawaii last year with their father but Spears has reportedly been 'focusing' on fixing her bond with her kids. 

In the clip, both Britney and Jayden could be seen standing outside of what appeared to be a restaurant. 

The pair stood side-by-side as they looked at the camera, and at one point, the singer planted a kiss on Jayden's head. 

The reel then cut to Spears and her son sitting at a table inside the crowded eatery as they stayed warm by a roaring fireplace. 

As she situated the phone camera on the table, Jayden offered a lighthearted 'Hello' followed by the two wishing her fans a 'Merry Christmas.' 

In the caption of the post, Britney expressed her gratitude and excitement to have had the opportunity to be with her boys for the holiday. 

She penned to her 42 million followers, 'Best Christmas of my life!!! I haven't seen my boys in 2 years!!!'

'Tears of joy and literally in shock everyday koo koo crazy so in love and blessed!!! I'm speechless thank you Jesus!!!'

Britney and her youngest child seemingly had a blast on the holiday, although her other son didn't make an appearance in the clip.  

The reunion comes shortly after a source informed Page Six earlier this month that the Toxic hitmaker is working towards 'rebuilding' her bond with Jayden and Sean Preston. 

'She and her sons are really focusing on rebuilding their bond,' the insider stated, and added they are on the road to being 'super close' once again. 'These things are a process in every family dynamic.'

Last month in November, a separate source revealed to Page Six that Spears reunited with Jayden after years of estrangement. 

At the time, the insider shared that, 'They have been spending a lot of time together.'  However, Sean Preston was still in Hawaii at the time of the reunion. 

'Britney is thrilled to have her baby back. Everything is moving in the right direction,' the source stated. 

Jayden reportedly reached out to his mother and an insider told Us Weekly that he 'is spending time back in California but does not live with Britney.' 

A few months earlier in September, Britney penned a sweet birthday tribute to her sons alongside throwback photos. 

The singer wrote, 'This month is my boys' birthdays !!! Happy Birthday babies and I hope you get all your wishes and more!!!' 

Also last month, the pop star made her final child support payment to ex Kevin Federline after Jayden's 18th birthday. 

The star has also gotten on good terms with her mother Lynne and brother Bryan Spears after their estrangement. But she has yet to mend her relationship with her father and sister, Jamie Lynn Spears. 

Earlier this month, Britney spent time with her older brother as he joined her in Mexico amidst her relaxing vacation. 

Last year in August, the pop star and her older sibling seemingly set aside their differences following her split from Sam Asghari.

At the time, he had moved into her mansion to be by her side during the divorce and a source told Page Six, 'He's been staying over and helping her alongside a therapist.'

Earlier this year in May, Bryan appeared on her Instagram page as the pair enjoyed a trip to Las Vegas.

She had shared various clips on social media that had captured special memories from the trip, including visiting a luxury spa.

Just weeks earlier, the Baby One More Time songstress had ignited mental health concerns at the Chateau Marmont when she was spotted being escorted out of the iconic hotel by emergency services.

In June, both the singer and her brother Bryan spent time at a bar in Mexico and a month later, he once again moved into her mansion.

At the time, she had split from boyfriend and former housekeeper Paul Soliz - but a source told TMZ that he had moved in simply because it made sense to stay under one roof due to spending a lot of time together.

On December 2, Britney celebrated her 43rd birthday - and was also declared legally after her divorce from Sam Asghari was finalized seven months earlier. 

She kept her followers updated during the trip by sharing various posts to Instagram - such as posing in a hot pink bikini while lounging under the sun. 

The performer deleted one of her recent dancing videos filmed during the vacation due to people saying 'mean things.' 

Just days before Christmas, Spears was spotted arriving back to Los Angeles after the three-week birthday getaway.   

After she touched down at an airport, the songstress was seen walking outside while cradling a stuffed rabbit.
