Phillippe, 36, reportedly becomes a father for the third time when former flame Alexis Knapp, 21, delivers daughter Kailani Merizalde Phillippe Knapp. "Ryan is aware of the situation [and] totally prepared to take responsibility should the child be his," a source tells PEOPLE of Knapp's daughter.
After being spotted together since December, Phillippe, 37, steps out with new gal pal Paulina Slagter for a dinner date at Los Angeles restaurant STK. "He and Paulina were very cute and held hands at their private table, tucked away from the rest of the crowd," a source tells PEOPLE.
