Liam Hemsworth calls Miley Cyrus his 'favorite little angel' in super sweet birthday message

Liam Hemsworth is sending some public birthday love to Miley Cyrus.

The 26-year-old actor Instagrammed an intimate pic of Cyrus on Wednesday, wishing her a happy 24th birthday. Cyrus appears to be topless in the snap, and holds up an adorably wrapped birthday gift, complete with a unicorn.

"Happiest birthday to my favorite little angel!" Hemsworth wrote.

The gesture is a rare one for the notoriously private Australian actor, who's remain tight-lipped so far about his rekindled relationship with Cyrus. Although Hemsworth has Instagrammed photos of the former Hannah Montana star before, the pics have all been flashbacks, such as this cute one capturing a moment between the two on the set of their 2010 film, The Last Song.

Cyrus showed off her birthday gifts from her beau on Wednesday, including star-shaped balloons, flowers, and a colorful ring.

"Best bday evaaaaaa!!!!!!! Thank you my loooooove," she wrote.

Of course, that's not the only ring Cyrus has received from the Independence Day: Resurgence star. Last month, the "We Can't Stop" singer talked about wearing her engagement ring from Hemsworth.

"It's very weird because this is, like, real jewelry and most of my jewelry is made out of gummy bears and cotton candy and they don't look that good together because they kind of mix up," she told Ellen DeGeneres. "So, sometimes I replace it with an actual unicorn or a Looney Tune. And he's like, 'What's going on?' And I'm like, 'Well, this isn't my aesthetic, but I'll wear it 'cause you love me.'"
