ET hit the red carpet last night for the premiere of The Vow, a love story that stars Channing Tatum and Rachel McAdams, who shared a laugh about McAdams' wardrobe during an interview.
"I feel like you're the prettiest little puppy ever," Tatum said in reference to his co-star's dashing necklace. "It's like a little bedazzled puppy collar."
"I think that's a compliment," McAdams, replied with an interrogative tone followed by laughter.
Also on the red carpet was "Friday" singer Rebecca Black, who admitted that she has wanted to see the movie ever since she saw the first trailer.
We also caught up with the couple that underwent the real-life love story and inspired the film—Kim and Krickitt Carpenter.
"I don't think you could have picked any better actor and actress to do it," Krickitt Carpenter said. "They complement our personalities wonderfully, and we really enjoyed the movie."
The Vow is in theaters this Friday (Feb. 10).
