Conor McGregor thinks Ronda Rousey will come back even stronger. And "The Notorious" is even more adamant that Donald Trump should stop talking.

TMZ caught McGregor at LAX in Los Angeles on Monday and the UFC interim featherweight champion had some advice for Rousey and some vitriol for Trump. Rousey lost her women's bantamweight title to Holly Holm via second-round knockout at UFC 193 on Nov. 14.

"Very tough fight," McGregor said. "Holly fought a great fight. I have much respect. This is the fight business. These things happen. Ronda will be back. True champions come back. And congratulations to Holly, the new champion."

Trump, a Republicion running for President of the United States, took particular satisfaction in Rousey's loss. Trump said over the summer that Rousey was a fan of his, but Rousey responded that she was actually endorsing Democrat Bernie Sanders.

Glad to see that @RondaRousey lost her championship fight last night. Was soundly beaten - not a nice person! — Donald J. Trump (@realDonaldTrump) November 16, 2015

McGregor was not aware of the harsh tweet. But he doesn't seem to be a big fan of the man. Luckily for Trump, McGregor is a native of Ireland and can't vote in the 2016 election.

"Donald can shut his big, fat mouth," McGregor said. "I don't give a f*ck about Donald Trump."

McGregor, who meets Jose Aldo at UFC 194 in a bout to unify the featherweight titles, has not spoken to Rousey since her loss, but when he does he'll have some sound advice.

"Defeat is the secret ingredient to success," he said. "True champions can conquer that, overcome it and come back. So I wish her all the best and that's it."
