Dec. 4 (UPI) -- It's hard to believe that Kaley Cuoco managed to keep her relationship with Big Bang Theory costar Johnny Galecki secret for two years, because the 28-year-old actress had no problem sharing PDA-filled photos of her romantic vacation with fiancé Ryan Sweeting.
The happy couple, who got engaged last September after three months of dating, visited the Bahamas over the Thanksgiving holiday.
"Thanksgiving travels w/ my partner in crime," Cuoco captioned a photo of their first-class plane digs.
Cuoco and Sweeting, 26, spent the rest of the holiday sharing jealousy-inducing snaps of the beautiful Bahamas, quite obviously enjoying each other's company.
