The mysterious three month disappearance of Fan Bingbing, China’s most famous actress, is over.

The 37-year-old actress, who reportedly had been detained by Chinese authorities over a tax evasion investigation, returned to public life Thursday, posting on the social media website Weibo for the first time since June, writing “I am unworthy of the trust of the society and let down the fans who love me.”

Chinese state media reports tax authorities have ordered Fan to pay 884 million yuan (US$130 million) in back taxes and fines, saying Fan won’t face criminal charges if she pays on time.

Earlier this year, Chinese authorities announced a crackdown on highly paid performers and “yin-yang contracts” – where a smaller-valued contract is reported to the government as a second, much larger-valued contract is kept secret.

Forbes magazine has named Fan one of China’s highest-paid celebrities for the past five years. She rose to fame in the late 1990s for her roles in My Fair Princess and Cell Phone, since expanding her popularity abroad, appearing as Blink in X-Men: Days of Future Past.

Fan had been signed to appear in the upcoming film Air Strike, starring Bruce Willis and Penelope Cruz.
