Biel celebrated her own birthday earlier this month, with the help of her husband, Justin Timberlake.

The "Sexy Back" singer threw his wife an epic roller skating birthday party in an effort to "Make America skate again." 

"You make me laugh. You make me smile. You make me LOVE. You make me want to be BETTER. Speaking of, it doesn't get any BETTER than you," Timberlake captioned a sweet Instagram post before the party. "Now, I know for sure that it's BETTER to be lucky than good. Ask me who the luckiest guy in the world is and I will tell you that you are looking at him. Happy Birthday, my heart."
