"When I close my eyes it’s you I see, You’re the reason why my heart still beats, My love is yours eternally, I live inside each memory," he wrote. "Your eyes light up the darkest night, Your kiss inspires the words I write, Your touch is all I need in life."
Mod continued: "Someday soon you’ll be my wife. You changed the world Avril, never forget. You are that mother [expletive] princess. You make me better I must confess. I’d whisper 'I love you' with my last breath.
"There’s so many words I wanna say, To my stunningly gorgeous fiancé, I’ll leave it at this til we runaway…. Baby I wish you a happy birthday."
Mod, real name, Derek Ryan Smith, concluded: "To my soulmate, you are such a gift in this world + to say I’m lucky to share a life with you is the understatement of the century…not to mention you are also the most beautiful woman that’s ever walked this earth. In two years together we have made so many memories but it’s just the start. Let’s runaway my love. Forever yours, mod."
Mod shared this sweet snap
The birthday honor came a month after the star was overcome with emotion when she received a Walk of Fame star in Hollywood.
Avril's fiance Mod Sun was there cheering her on, and posed for pictures with the 37-year-old who wore a punk red plaid suit with a black leather harness, before she changed into her high school hoodie which read "skateboarding is not a crime"; it was the same hoodie she wore 21 years ago when she first visited the iconic street.

The singer shared the cover of the 2002 album, featuring Avril wearing her best early aughts grunge outfit along with a lengthy, heartfelt tribute to the album and everyone who made it possible.
