"Alexis has told friends that the child is Ryan's," a source told People magazine on Monday.

The baby is said to be due in June, according to the report.

Sources in multiple media outlets have said that Phillippe will take responsibility if the child is his. TMZ is reporting, citing sources close to the actor, that he will wait to take a DNA test until after the baby is born.

"He's a good guy," a source told Us magazine. "He loves being a dad and takes being a dad really seriously."

The actor, 36, already has two children with ex-wife Reese Witherspoon. Phillippe, who split from actress Abbie Cornish in February 2010, has been recently linked to "Red Riding Hood" star Amanda Seyfried.
