Colton Haynes is officially engaged! The “Teen Wolf“ star announced his engagement to Jeff Leatham on his social media account by posting a photo of him kissing his fiancé under the fireworks. Haynes captioned the snapshot with, “I SAID YES!!!”

Leatham's proposal to Haynes was one to remember, Mirror noted. He popped the big question during the couple‘s romantic getaway in Las Ventanas al Paraiso resort in Cabo, Mexico.

The proposal included a personalized video message from Cher, who sang their favorite song, “I Got You Babe.” It was followed by several video messages from the pair’s family members and close friends, including Melanie Griffith, Serena Williams, Ally Maki and more.

After Haynes said yes to Leatham’s question, the proposal video showed a fireworks display while Bruno Mars’ “Marry You” was played in the background. The newly engaged couple danced to the song as they cried in happiness, according to the statement issued by Hayne’s rep to People.

“Jeff, you’re crying,” Haynes said in a video. “You’re the sweetest person in the entire world. I can’t believe you.”
