Who's the boss? Tony Danza might have some say in the matter, but rappers [artist id="2000082"]Rick Ross[/artist] and [artist id="1605088"]Slim Thug[/artist] took to Twitter over the weekend to lash out at each other after lyrics from the Miami rapper's leaked song "King Boss" hit the Web.

"She dated Slim Thug, but now she f---s with me," Ross spits on the track's second verse. "She finally made it to the biggest boss, luckily."

"WTF is that a diss," Slim Thug tweeted to Ross.

"Just threw [Rick Ross'] cd out the roof of the coupe," the Houston rapper later wrote. "[H]aters get no play in my ride."

According to Slim Thug, he reached out to Ross to get some clarity regarding the song but was unable to connect with the Teflon Don star.

Though the song appears to be dated, a rep for Ross had not responded to our inquiry by press time.

Slim Thug also tweeted that Ross' silence on the matter must speak for his intent, namely that the song was intended to be a fresh attack on Slim Thug. He continued to disparage Ross, eventually prompting one of the Miami rapper's crew members, Torch, to chime in.

"Not u2 [Slim Thug] aka Slim Sukka," Torch wrote. "I promise this ain't the attention u want..."

Ross, for his part, weighed in on the matter, albeit briefly, with just one message posted on Twitter. "[R]eal n---as pick up phones," he wrote. "A boss would kno better!!#trillsh--."

The pair have collaborated in the past, but it remains unclear if there was previous friction between the two artists, who both use "Boss" nicknames.
