Christina Aguilera is being every bit the bestfriend that Demi Lovato deserves post her rehab and fatal overdose. Christina has been a source of support and has been commenting on Demi’s recovery pictures, reports Dailymail.co.uk.

Lovato uploaded a picture of herself — the first after her fatal OD and subsequent rehabilitation — in her jijitsu uniform with sweaty, messy hair. She captioned the picture with #nevergiveup. Christina left multiple sweet comments on the picture, including, “I’ve missed you so very much (sic)” and “And we keep on tickin – till the end of time — I looooove youuuuu! Can’t wait to continue to have you by side now (sic).”
