On Saturday, after three months of detention at the Riyadh's Ritz Carlton hotel, Saudi billionaire Prince Alwaleed bin Talal was released with "no charges" ... and his daughter couldn't have been happier. 

In a tweet she posted on Sunday, Reem bin Alwaleed expressed her joy upon her father's release.

"You've lit up the world, you are my world," she wrote in a tweet alongside a photo of her father. The tweet has since gone viral, amassing over 2,000 re-tweets at the time of writing.

Lots of "Al hamdilla 3al salemi" soon followed

"God bless"

Others commented on his appearance: "Tell him to keep the beard ... very stylish"

"He looks just like this actor"

The news came just hours after the billionaire had told Reuters in an exclusive interview that he is expected to be released 'soon'

The news came just hours after the billionaire, also known as "the richest Arab," told Reuters he expects to be released very soon, with his name cleared of any wrongdoing.

At the beginning of November, Prince Alwaleed, along with hundreds of other prominent Saudis, were detained as part of a wide-reaching anti-corruption probe. 

Members of the royal family, former and current government leaders, and prominent businessmen were also detained in the so-called "purge".

Other prominent figures were released within weeks or months, agreeing to financial deals to settle the charges against them. 

"Most detainees faced with corruption allegations by the committee agreed to a settlement. The necessary arrangements are being finalized to conclude such agreements," the kingdom's attorney general Saud al-Mojeb said in December.

Alwaleed said "all is a misunderstanding"

In an interview with Katie Paul, Reuters correspondent in Saudi Arabia, Alwaleed said the whole incident was just a "misunderstanding".

"There are no charges. There are just some discussions between me and the government. Rest assured this is a clean operation that we have and we're just in discussion with the government on various matters that I cannot divulge right now. But rest assured we are at the end of the whole story. And I'm very comfortable because I'm in my country, I'm in my city, so I feel at home. It's no problem at all. Everything's fine," he said.
