Is that a belly – or a baby bump?
As the latest round of pregnancy rumors swirl around Eva Longoria Parker
, good pal Mario Lopez says she's falling back on her usual coping mechanism: Humor.
"We get a laugh out of it," Lopez told PEOPLE Thursday after hosting the live finale of MTV's America's Best Dance Crew
in Burbank, Calif. "She's really cool. She just takes everything as it comes."
The Desperate Housewives
actress, 33, has been the focus of a bump-watch
, ever since she tied the knot
with husband Tony Parker in July 2007.
This week, speculation picked up again when she was spotted wearing a long, flowy top in Los Angeles. And just last month, she told reporters she "can't wait
" to have children.
To date, the actress's rep has consistently denied the pregnancy reports.
While Longoria Parker doesn't always pay attention to the rumor mill, she is definitely aware of the chatter, said Lopez.
"She doesn't [read about herself], but I think people tell her – and she gets a kick out of it," he explained. "She's very calm and very secure. She knows people are always going to [talk]. That stuff doesn't bother her."
