Liv Tyler, who says her “heart longed for a second child,” shared an adorable black and while baby bump photo Sunday on her Instagram account.

The 37-year-old mother to nine-year-old Milo with ex-husband Royston Langton, told Town & Country she is truly enjoying her pregnancy.

“The most fun thing about being pregnant is having those mom hormones flowing around,” Tyler said.

“You’re more present in your body and it’s making me a better mother for Milo. You become more like a child. When you’re tired, you have to sleep immediately. When you’re hungry …”

And that’s when she shared one of her favorite perks of being pregnant — guilt-free indulging.

“It’s fun not being on a diet or thinking, ‘Oh my God, I have to go to SoulCycle every day,’ ” she said.

It seems everything is going well for Tyler, who is fulfilling a dream by starring in HBO’s The Leftovers.

“I mean, for seven years I’d been saying I wanted to do an HBO show with an ensemble cast,” she said. “And I wanted the house in the country. And getting to have another child? If you knew me well, they were the things my heart longed for. And they all came together, like a speeding freight train, in one year.”
