Jake Gyllenhaal had one of his famous exes in mind on Saturday -- no, not Taylor Swift, but Natalie Portman, who's now engaged (to Benjamin Millepied) and pregnant.

Presenting Portman (they were first linked in 2002 and were spotted on a date in 2006) with a Desert Palm Achievement Award for her role in Black Swan, Gyllenhaal good-naturedly laid into his Brothers costar.

"I first met Natalie at a Star Wars convention waiting in line for her to sign my Queen Amadala doll and I'm really hoping she wins the Oscar," Gyllenhaal, 29, joked, "Because if she does, then that doll is going to be worth a s***oad of money!"

The single-again actor continued of his expectant pal, 29: "She's recently announced that she's going to be a new mom to a child who will probably need therapy after seeing Black Swan," he said of the pitch-black psychological thriller about an emotionally disturbed ballerina.

He added that Portman's child "will most likely be gorgeous like his or her mom, even with a shaved head." (Portman went bald in V for Vendetta.)

Cracking up the crowd, the Love and Other Drugs actor likened Portman to "the Audrey Hepburn of our generation. She's graceful, has amazing eyebrows, and is talented, really short, funny, smart, dedicated, incredibly kind and Jewish!"

One minor hiccup in their friendship? Her vegan (no meat or dairy) diet. Explained Gyllenhaal: "It does get hard when you're out to dinner with her."
