Beyonce's baby clock is ticking!

"I always said I would have a baby at 30," the singer, who turns 30 in September, said on Monday's "Piers Morgan Tonight."

"But," she teased, "I also said I was going to retire at 30." (The star, whose new album, "4" drops Tuesday, added that she has no intention of retiring anytime soon.)

Although the timing of her family plans remain up in the air, one thing is certain: She and hubby of three years, Jay-Z, are solid as a rock.

The rapper-mogul, 41, is a "good man," gushed the notoriously private singer. "He is amazing," she added, explaining that they made a "marriage pact" to keep certain things private.

"Jay and I have kind of made a decision that we want to be known for our music and not our relationships or scandals."
