Washington, Nov 28 : It looks like Olympic golden boy Michael Phelps is taking his relationship with girlfriend to the next level – the swimmer has invited his ladylove to spend Thanksgiving in Baltimore with him and his family.

Phelps has been dating Las Vegas cocktail waitress Caroline "Caz" Pal, 26, for about two months.

The couple met after Phelps’ record-setting performance in Beijing last summer.

"She''s there [in Maryland] meeting his family for the first time," People quoted a source, as saying. (ANI)
