The ad featured actress Sydney Sweeney.

Titmus said it sexualised women's sport.

Other elite athletes joined the criticism.

The ad came from a sports prediction company.

As a separate matter, Titmus announced her engagement.

Her fiancé has been named as Mac Powell.

She shared the message 'Forever' on social media.

The engagement news was unrelated to the ad.
