Rodriquez definitely seemed to enjoy his day. He posted a hilarious video of the madness -- and singalongs -- that ensued at his birthday bash.

\"I am so incredibly fortunate and grateful for where I am in my life,\" he wrote in the caption of his post. \"I thank the good Lord for my blessings, today and every day.\"

If their upcoming wedding is anything like these celebrations, we can't wait.
