It seems to be a very happy birthday for Miranda Lambert, indeed.
As the "Vice" singer rings in her 33rd birthday on Thursday, boyfriend Anderson East, 28, is marking the occasion with a super sweet post on Instagram.
"Happiest of birthdays to this beautiful Texan!," he captioned a black-and-white shot of the couple wearing clear ponchos, gazing adorably at each other in front of Niagara Falls. "I'll celebrate you today and everyday ahead."
Fittingly, East added a red heart emoji to the end of his post after tagging Lambert.

Lambert's birthday comes about a week before she's set to release her new album, The Weight of These Wings, which features two new songs co-written with her beau.
And just last week, Lambert and East hit the red carpet together for the CMA Awards in Nashville. Showing off her curves in a gorgeous black gown, Lambert couldn't help but gush about her "sweet" guy on Instagram. "I'm a lucky girl!" she wrote.
