Adriana Lima has confirmed she is expecting her third child with partner Andre Lemmers III.

The 40-year-old supermodel announced the exciting news she is expanding her family in her first ever TikTok video.

In the video Adriana shared snippets of occasions her boyfriend has scared her, from jumping out at her, or spooking her when she is brushing her teeth.

The Victoria's Secret angel decided to reciprocate this, and planned her own "payback".

Writing in the video, she shared: "Andre likes to scare me... but today is payback."

Adriana's surprise was revealing to Andre they are expecting their first baby together while he was asleep.

If this was Adriana's TikTok debut, we are hoping for even more good news on the social media platform.
