Tesla (TSLA) CEO Elon Musk on Monday morning posted on Twitter that he "just deleted his Twitter account." He also changed his Twitter handle to "Daddydotcom" — a possible reference to Father's Day.

The account remains active on Monday afternoon, while Tesla has yet to respond to Musk's tweet. It's unclear whether Musk posted the comment in jest.

Musk has a history of posting controversial and attention-seeking comments on Twitter and his tweets have also landed him in legal trouble with the Securities and Exchange Commission (SEC). He tweeted in August that he was going to take Tesla private at $420 a share. This drew the ire of the agency, which later ordered him to seek pre-approval from the Tesla legal counsel before tweeting and to pay a $20 million fine. 

In February, Musk tweeted that Tesla plans to manufacture 500,000 vehicles in 2019, which resulted in the SEC filing a motion saying that he violated the terms of his agreement.  

Musk also faced controversy and legal troubles after he used Twitter to refer to a diver who rescued 12 boys trapped in a Thailand cave as a pedophile. This led to the diver, Vern Unsworth, to sue Musk for defamation.

In September, Musk smoked marijuana and drank whiskey on a popular podcast, which contributed to a 9% percent one-day drop in Tesla's share price.
