Ariarne Titmus has criticised a sports betting advertisement.

The ad included actress Sydney Sweeney.

Titmus claimed it sexualised women's sport.

The advertisement provoked a backlash.

Other elite athletes also spoke out.

The ad came from a sports prediction company.

As a separate matter, Titmus shared her engagement news.

Her fiancé has been named as Mac Powell.

She shared the message 'Forever' on social media.

The engagement news had nothing to do with the ad.

Titmus's comments contributed to a public backlash.

Athletes across different sports joined in.
