Selena Gomez and Britney Spears share sweet Instagram exchange

Amid Britney Spears' ongoing conservatorship drama, the singer is staying positive -- most recently shouting out fellow pop star Selena Gomez for the unexpected gift that arrived in her mailbox.

The "Toxic" singer recently shared an adorable package Gomez sent her: a purple tie-dye bikini along with several offerings from her Rare Beauty makeup line.

"Ok guys ... great news," Spears, 39 gushed in the caption. "When I woke up I got a very cool box with a bikini in it and my favorite three make up products from @SelenaGomez!"

The Grammy winner endorsed Gomez's makeup line in the appreciative caption and told fans, "Her shimmers are really fun and her spritz for your face before makeup is bomb and smells very good!"

Spears noted that the gift came at the perfect time, too, hinting that she needed a little pick-me-up.

"Selena .... Thank you for surprising me with this gift … I’ve been looking for shimmers," she wrote.

The "Lose You to Love Me" singer was ecstatic Spears enjoyed the gift and gushed in the comment section, "This makes me so happy! I hope you enjoy it - love you so much."

Gomez, 28, also enclosed a crown and black heart emoji in the comment.

This isn't the first time the two artists publicly supported each other. In May, Gomez shared a throwback video of her younger self enthusiastically singing along to Spears' 2000 song "Don't Go Knockin' on My Door."

Spears called the video "the most adorable thing I’ve ever seen" in the comment section, leaving a shocked face, red heart and dancing woman emoji.
