Model and TV star engaged after four years – just look at that ring!

Congratulations are in order for BBC presenter Reggie Yates and his long-term girlfriend Tia Ward.

The couple, who have been together for four years, took to Instagram yesterday to share the happy news of their engagement which happened earlier this month.

Model Tia revealed the news by posting this snap of her gorgeous gold ring, with the caption, "B I R T H D A Y S P A R K L E: 'I have decided to stick with love, hate is too great a burden to bear.' Happy Martin Luther King Day."

A birthday, a national holiday AND an engagement? Sounds like Tia has a lot to celebrate this month!

Although Tia and Reggie have been together since 2011, they only went public with their relationship in 2012, after being pictured on holidays together in St. Tropez.

TV presenter Reggie, best known for his hosting work on The Voice UK, popped the question while the pair vacationed in Brazil over New Year's. Tia wrote about the incredible trip on her blog last week, saying, "Where to even begin. Our time is Rio de Janeiro was spent lounging in the sun, exploring the city, taking pictures, immersing ourselves in the culture & eating plantains and steak till our top buttons had to be undone."

A dream trip by all accounts!
