The group eventually entered the establishment and sat down together for dinner.

Cinco de Mayo is an annual celebration held on May 5 in honor of Mexico’s victory over the Second French Empire at the Battle of Puebla in 1862, led by General Ignacio Zaragoza.

Cinco de Mayo is more popular in the United States than Mexico and is associated with the celebration of Mexican American culture.

Celebrations began in California, where they have been celebrated annually since 1863.

Finally, the couple and their friends concluded their time with Craig and made the short walk back to their parked car.

Admiring photographers again snapped photos of McPhee and Foster as they pulled out of the parking lot.

McPhee was in the back seat while her husband was behind the wheel and a male companion in the front passenger seat.

In another photo, the former star of the Broadway version of Waitress turned her attention to her cell phone.

Just two days earlier, the couple took to their respective Instagram pages to promote Foster’s upcoming concert in Las Vegas called Intimate Evening With David Foster: Hitman Tour.

The two Sin City shows will be held June 23 and 24, with McPhee as a special guest vocalist.
