The Tik Tok singer signed on earlier this year to advertise the firm's watches.
And she appears in a new ad campaign for the Baby-G line, wearing several of the colourful timepieces on her arms.
The new ad comes as the 23-year-old singer, real name Kesha Sebert, joined an American campaign to promote the First Amendment.
She is featured in a new poster for the national public education campaign “1 For All”, which aims to educate and promote awareness about freedom of speech and expression, according to USA Today.
