Liam celebrated the songstress ringing in her 24th year with a very suitable and Miley-esque gift.
The 26-year-old actor took to Instagram wish his love a "Happy Birthday".
"Happiest birthday to my favorite little angel!," he announced, alongside a snap showcasing his impressive wrapping skills - showing he decorated a gift box with gold string, colorful heart and peace sign stickers and a unicorn tag.
And the birthday girl was VERY happy indeed.
Sharing her loot on the picture sharing site, she gushed, "Best bday evaaaaaa!!!!!!! Thank you my loooooove!"
The singer had received a very pretty rainbow, gem-filled ring, which she praised.
"Look at datttt Rainboooowwwwwwww rock! You always know how to make my "grubby little kid fingers" SHINE!!! (P.S. please take notice of that beautiful packaging!!!!)"
Clearly Liam has been listening to Miley's comments about her the 3.5-carat cushion-cut, vintage-style Neil Lane diamond engagement ring that he proposed with a few years ago.
The singer recently admitted to Ellen that despite the sentiment behind it, the ring itself wasn't really for her!
“This is really weird, because this is like real jewelry and most of my jewelry is made out of gummy bears and cotton candy … they don’t look that good together because they kind of mix up,” she laughed.
“So sometimes I replace it with an actual unicorn or a Looney Tune. And [Liam's] kind of like, ‘What’s going on?’ I am like, ‘This isn’t really my aesthetic, but I’ll wear it because you love me.’”
The couple have been ramping up their romance, after making their first public appearance together in three years.
Miley and her fiancé were the picture of love when they stepped out together for Variety’s Power of Women luncheon in LA back in October.
The young lovers didn’t hesitate to pack on the PDA!
"She wrapped her arm around him and leaned her head against his shoulder," an onlooker said to E! News.
The A-list couple, who called off their engagement back in September 2013, caught the world by surprise when they reconciled at the end of 2015 in the beach town of Byron Bay.
