"Friends" must've had an influence. This week's PEOPLE Magazine coverboy Bruce Willis , 45, who's in the midst of a May sweeps guest stint on the hit NBC sitcom, is still going strong with Spanish model-turned-marketing-executive girlfriend Maria Bravo, despite published rumors to the contrary. Furthermore, he and Bravo have even been spending time with Bruce's wife of 10 years, Demi Moore, from whom he is now estranged. "We spent some time together (with Moore)," Bravo tells PEOPLE. "She's a sweet lady, very sweet. Because she has a relationship with someone else, that helps." That person in Moore's life is martial arts instructor Oliver Whitcomb, 30.
