Ugly Betty's Eric Mabius and his wife, interior designer Ivy Sherman, have welcomed a second son, named Rylan Jaxson Mabius, his rep confirms to PEOPLE.

The baby was born Sunday in New York City and weighed a little more than 10 lbs., a source confirms to PEOPLE.

Mabius and Sherman are also parents to Maxfield Elliot, 2.

The family recently relocated from Los Angeles to New York, where Ugly Betty is filming. With costar Rebecca Romijn expecting twin girls in January, Mabius told PEOPLE in September that he plans to bring his children to set.

"Oh, all the time," he vowed. "Max is a hit on set."
