One of the most memorable celebrity social media blunders belongs to Lorde. The singer got backlash for an Instagram post that clearly referenced Whitney Houston in a caption for a photo of a bathtub. It read: "And iiii will always love you." 

Houston died in 2012 when she accidentally drowned in a bathtub in Los Angeles.

After realizing what she did, Lorde quickly deleted the post and apologized. "Extremely extremely poorly chosen quote," she wrote. "I'm so sorry for offending anyone — I hadn't even put this together I was just excited to take a bath. I'm an idiot. Love Whitney forever and ever. Sorry again."

Also, let's not forget the time when Charlie Sheen accidentally tweeted his phone number to his more than 5 million Twitter followers while attempting to send a direct message to Justin Bieber.

Sheen reportedly was eating dinner at a restaurant in Las Vegas when he tried to get the pop star to give him a call. Everyone immediately started retweeting it and the number has since been disconnected, and the tweet has been deleted. 

According to a source at the restaurant, Sheen’s phone was bombarded with calls and text messages. "Charlie's phone immediately went into meltdown. It was ringing wildly, and he got 1,800 text messages in minutes. Charlie saw the funny side and answered the phone a few times, saying things like 'Ray's Pizza' and 'Winning'" they said.

One thing we can definitely learn from these pictures is that you can delete a tweet, but a screengrab can last forever.
