It took Miranda Lambert three weeks to post pictures of her star-studded Texas birthday party at Billy Bob's In Texas. But when she posted, she did it in four bunches on Instagram, sharing many photos with fellow country stars Lainey Wilson, Dierks Bentley, Little Big Town, and more. Miranda captioned the first birthday photo dump with photos of her and their friends performing on stage, "3 weeks ago today. My Billy Bob's Texas boot scootin' 40th. The absolute best birthday my Texas heart could ask for. Thanks, @cameronruthm, for putting it all together and for the prettiest balloon arches I've ever seen. And huge thanks to my pals and heroes @adamhoodmusic @randyrogersband @wadebowen for over 20 years of friendship and for entertaining us all night. Thanks to my city mouse friend @telemitry for going country, for the late-night jams, and even for wearing fringe. Thank you, @tylerjconrad, for capturing all the fun." She continued, "I got to enter a new decade with dear friends and family at my favorite honky tonk @billybobstexas . There are so many pics full of joy and smiles, so I'm gonna keep on posting'! That's why it has taken me 3 weeks to post these. I've just been overwhelmed with gratitude and love for everyone that came to scoot your boots with me. I love all of y'all so so so much. Cheers to 40!" See that post here.
