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."
