NEW YORK (AP) -- Kristin Cavallari and Jay Cutler have added another boy to their team.
The couple welcomed a son Wednesday named Jaxon Wyatt, her publicist confirms.
Cavallari posted about the birth on her official Twitter account.
27-year-old Cavallari and the 31-year-old Chicago Bears quarterback are already the parents to a 20-month-old son, Camden.
The couple married last summer in Nashville.
Cavallari starred in the MTV reality series ''Laguna Beach'' as a teenager and then joined its spinoff ''The Hills'' when Lauren Conrad left the show.
She now co-hosts the E! lifestyle series ''The Fabulist.''
