Actress Liv Tyler has finally confirmed she is set to wed her partner Dave Gardner after gushing about her fiance in a sweet Instagram post.

David Beckham's sports agent pal reportedly proposed to the Armageddon beauty last December, while she was pregnant with their first child together.

The news only hit headlines in February, when Tyler was spotted wearing what appeared to be a large diamond engagement ring on her left hand during an outing in New York City.

Now, almost a year after Dave popped the question, she has publicly acknowledged the marriage rumours in a romantic social media message.

The couple began dating early last year and welcomed a son named Sailor Gene in February.

The fiercely-private actress, whose father is Aerosmith frontman Steven Tyler, has yet to comment on plans for her big day - her second trip down the aisle.

Liv was previously married to rocker Royston Langdon, the father of her 10-year-old son, Milo.

Dave also has another child, seven-year-old son Gray, with his ex-wife, British actress Davinia Taylor.
