With fiancé Cash Warren by her side, Jessica Alba can't help gushing about her impending baby joy.

"It's awesome," she told PEOPLE Thursday in L.A. at Glamour magazine's kickoff for V-Day's 10th Anniversary. "It's the best time ever. I have two movies coming out, a baby, a fiancé – everything."

The 26-year-old actress, who's due in early spring or late summer, said the pregnancy has been smooth so far. But, she admitted, "I'm more tired, more hungry than normal."

Alba – who also recently announced her engagement to longtime boyfriend Warren, 28, the baby's father – also said she's enjoying a rare break from acting.

"I don't know if anyone wants me in their movies [when I'm] six months pregnant," she joked. "I'll get the fire and I'll want to work again, but right now it's a time to relax and sit back."

For now, the actress is focused on a more personal project: "I bought a new house a couple weeks ago. I'm in nesting phase."

Later, Alba joked about her growing baby bump as she performed "My Short Skirt," a scene from Eve Ensler's Vagina Monologues.

"I hope [my dress] won't pop while I'm up here," she said. "And if it does, you're all women, and I think you'll understand it. [When you're pregnant], your breasts are engorged and your stomach is getting bigger. . . . And the ***, too, that's getting bigger by the second!"
