Miley Cyrus must be pretty darn persuasive, because it didn't take long to convince her older brother Trace to get some new ink -- immediately after he tweeted about how much he regretted his tattoos.

The heavily-tatted Trace Cyrus shocked fans last night (Sept. 30) when he tweeted that he "ruined his body" with the art. The Metro Station singer wrote:

As it turns out, Trace didn't need that much convincing, responding to Miley:

Our take? When you have as many tattoos as Trace does, what's one more? Plus, Miley may even be willing to tattoo this one on him -- considering she's tattooed people in the past.
