The first thing a new Hollywood couple has to do to confirm their relationship is to walk the red carpet together. It proves to the world that the relationship is legit, especially when there's a lot of gossip going around.
The couple seemed to be color coordinated as well. Pratt wore a black and silver tie to match Schwarzenegger's sleek silver gown.
The couple have been together just under a year. After many sightings, family outings and vacations, the couple got engaged in January.
"Sweet Katherine, so happy you said yes! I'm thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!" Pratt wrote on his Instagram post, announcing the proposal.
"My sweet love. Wouldn't want to live this life with anyone but you," Schwarzenegger captioned on her Instagram post that had the same picture of the couple embracing and highlighting a dazzling engagement ring.
Plans for the big day are currently underway, and E! News has reported that the couple will probably wed some time this fall or winter, in Martha's Vineyard. Pratt is very much involved with the planning as is Schwarzenegger's mother, Maria Shriver.
