The 'Glee' co-creator posted a gushing tribute to his bride-to-be to mark her 46th birthday and praised her for her beauty, her heart and how hard she works.

He wrote on Instagram: "When was this photo taken? 1940? '50? '70? Last summer? It's this timeless beauty's birthday today. She was born with endless gifts - big blue eyes, a brain and heart overflowing with curiosity, generosity and possibility and those heartbreakingly long legs that go on and on - but she never rests on any of them. Gwyneth, you are the hardest working person I know.

"From your first cup of coffee in the morning to your last cup of whiskey at night. From the gym to the office to homework at the kitchen table. You give us all of you, all the time. And always with a smile (well, almost always). Maybe that's why, even though you are the best person ever, you keep getting better every year. Happy birthday, Love. (sic)"

Meanwhile, Gwyneth recently insisted neither she or Brad want anymore children.

She said: "Neither of us want more kids. We're on the same team. It's always tricky with kids and trying to gently blend families, and it's hard."

And the 46-year-old actress gets on really well with her ex-husband Chris Martin, with whom she shares kids, Apple and Moses.

She added: "Chris and I had days in the beginning when it was really hard. I didn't want to see him. I didn't want to eat dinner with him, and he didn't want to eat dinner with me. In our case, we're really lucky because we see eye to eye. Chris and I are really lucky because we really agree fundamentally about how to raise the children. We have similar principles and values. I absolutely trust him ... I'm just going to focus on what I love about Chris, and there's so many things to love about him, and I still do that."
