Inside Hollywood's Cutest Nursery Rooms

When it came time to decorate the nursery for her second daughter, Haven Garner, Alba told PEOPLE, "I went on design blogs and pulled inspiration." The result: an airy pink-and-blue accented space with plenty of room to grow and play with 3-year-old big sister Honor Marie.

The singer-songwriter and husband Ty Murray kicked up the country charm for son Kase Townes's nursery. Decorated with reclaimed barn wood, the down-home room is filled with mementos from Mom and Dad, including Murray's baby cowboy boots and a mini guitar from Jewel.

When the comic was pregnant with her surprise, son Eli Benjamin, she chose to convert part of her one-bedroom apartment in New York into a baby room. "It came out really well," says Dratch. "It looks like a real, albeit tiny, room."

The boxer-turned-entrepreneur's nursery for daughter Sydney is filled with vibrant – and girly! – pink accents. But the focal point is a photo of the new mom as a baby with her father, Muhammad Ali, that hangs above the crib: "It is like a light shining down on her from my dad," Ali tells PEOPLE.

The Rascal Flatts crooner and wife Allison chose luxe details for daughter Madison Leigh's room. The classic yet girly space features crystal chandeliers, a hand-painted mural on the ceiling with lines to "Twinkle Twinkle Little Star" and the topper – a tiara from Allison's pageant days.

The reality star and husband Jason Hoppy didn't know the gender of their first child until she arrived, so they went neutral with the baby room: yellow! After welcoming daughter Bryn Casey, the new parents didn't change anything to the bright, sunny wildlife-themed nursery. "Everything is fun, playful, and whimsical," says Frankel.

Before the arrival of his fraternal twins, Lydon Edward and Hartley Grace, the Don’t Forget The Lyrics! host and his fiancèe Carin Kingsland had conflicting design views about the nursery. A compromise produced an elegant purple-and-gray space the babies – and their parents! – love. "It's the heart of our home," McGrath tells PEOPLE.

The actress and husband Brady Smith incorporated DIY elements into the lavender-hued room of daughter Harper Renn. While Smith stenciled the white birds along the wall nearest to the crib, Thiessen added bedding and a white tree from her new nursery decor collection, Petit Nest.
