Beyonce takes rare selfie with Mariah Carey as she visits singer at holiday concert

She rarely ever posts to social media. But Beyonce took a surprise selfie on Sunday night - and with none other than fellow super star Mariah Carey.  

The chart-topper, 35, paid Mariah, 46, a visit to her concert at the Beacon Theatre in New York City when she took an epic snap with the star of the night. 

'I love you @beyonce,' Mariah gushed in the caption of the photo, which appeared to be taken backstage of her show. 'thank you sooooo much for coming out tonight! (lips emoticon).'

The star is only performing a few more days of her show Mariah Carey: All I Want For Christmas Is You, and it seems Beyonce was keen on catching her before her series ended.

Beyonce looked casual and rather low-key with hardly a stitch of makeup on.

She did, however, cut a very stylish figure with her black wide-brim hat, bomber jacket, and silver chain necklace.
