No joke! Bruce Willis and his wife Emma Heming-Willis really did welcome their first baby together on April Fools’ Day — Monday, April 1st. Daughter Mabel Ray Willis weighed 9 pounds, 1 ounce. Mabel is the fourth daughter for Willis, who has three — Rumor (23), Scout (20) and Tallulah (18) — with ex-wife Demi Moore. In addition to tackling the joys of a new baby, Willis has several movies hitting the big screen this summer: Moonrise Kingdom opens in May, and GI Joe: Retaliation opens in June.
