Has Hilary Duff's rumored new romance with hockey player Mike Comrie thawed her chilly feelings toward ex-boyfriend Joel Madden?

That's the word from Us Weekly, which says the toothsome starlet, 19, sent a text message to her self-described "first love" after his impending fatherhood with Nicole Richie was confirmed during their recent sit-down with Diane Sawyer.

"After they appeared on 'Good Morning America,' Hilary breezily texted Joel congratulations on the pregnancy, and Joel warmly responded," an adverb-happy mole tells the mag.

Duff's alleged well wishes are quite a change from her previous stance on their romance, which began shortly after she and Madden called it quits late last year after two and a half years of togetherness.

"With the amount of time that we had invested in each other, I felt disrespected that he moved on so quickly," she recently sniffed to Seventeen. "But some people don't want to deal with how they feel, so they cover it up. Rebound! I shouldn't say that. You know what, though? Now I don't care."

According to Us, Duff's kinder, gentler attitude is a result of her budding romance with Comrie, 26, whom she's reportedly been seeing for several weeks.

"Hilary plays it coy, but she's really into him," says the snitch, who describes the lantern-jawed New York Islander as a "great guy." "He's the first she's been serious about since splitting with Joel ... They're just great together."
