Kennessy’s partner just pulled off the most romantic move of 2017... with a bath bomb.

A woman has been given a promise ring via a bathbomb and this is how it went down:

Twitter user “Kennessy” was given a bright blue bath bomb by her boyfriend. Sweet enough.

It dissolved in the bath.

The water turned blue.

And a little plastic bubble rose to the surface.

She looked inside and found a diamond promise ring.

She posted the whole thing to social media with the caption: "Sooooo this happened yesterday...Shook".

'Shook' indeed. The best part about it? The ring is a promise ring, not an engagement ring, Kennessy has confirmed in the comments.

Who knows what her beau has in mind for a proposal.

It all begs the question.... But, how?

He could have made the bath bomb himself.

Or it might have been organised through a company such as Peal Bath Bombs, which specialises in these sort of proposals.

Regardless, Kennessy's post has gone viral on Twitter. It's been re-tweeted more than 30,000 times.

The public consensus? Her boyfriend is a keeper.
