It looks like former "Arrow" and "Teen Wolf" star Colton Haynes is off the market. Over the weekend, Haynes said yes to the proposal from Jeff Leatham, celebrity florist. The happy couple first announced their relationship last month on Valentine's Day. This coming after Haynes came out as gay in early 2016. They have been vacationing in Cabo San Lucas, Mexico, and the proposal came on Sunday.

The proposal

From the looks of it, Leatham did not mess around with this proposal. It included a video message from Cher, Serena Williams, Melanie Griffith, and many more.

They also had video messages from their friends and family before ending it with a dance to "Marry You" by Bruno Mars while fireworks went off in the background.

Colton Haynes shared the big news on Twitter and seemed to be over-the-moon happy:

A little help from celebrity friends

In an interview with People, Haynes said, “I’m so blessed and happy for the future and my life together with Jeff."

When you have Cher as the lead-in to your proposal, you can't really go wrong. Both Colton and Jeff thanked Cher for the video message on Instagram. He captioned it, “Thank you @cher and @pauletteakapauly – for helping making my Proposal Evening Epic – I got you Babe never sounded so good right before @coltonlhaynes said YES!!!

So Appreciative and much love.”

The couple have been vacationing in Mexico and have been sharing photos of the trip all along. Yet, Colton Haynes did not know what the actual trip was about. They both shared photos on Friday, as Haynes captioned his, “I can’t put into words how truly happy I am right now. So full of love.”

In his post, Leatham said, “Surrounded by beauty inside and out life does not get better than this thank you @coltonlhaynes.”

From there, things took a turn for the better and the proposal happened.

The couple arrived together as a dating couple, but they will leave as an engaged couple. There are no details as to when the actual wedding will be taking place, but they are enjoying the engagement time for right now.
