Donald Trump is shaping up as the 'entertainment president' and his latest appointment only serves to reinforce that notion.

Mr Trump has selected Linda McMahon to lead his Small Business Administration (SBA), his transition team announced Thursday (AEDT).

Ms McMahon, 68, was a high-profile Trump backer during his presidential campaign and has run for a senate seat twice, but is best known as a professional wrestling magnate.

Wait, professional wrestling? Do you mean WWE?

Yes. Yes we do.

Ms McMahon co-founded World Wrestling Entertainment with her husband Vince McMahon in 1979 in South Yarmouth, Massachusetts.

She is also the former chief executive of the company, of which her family owns a majority stake.

WWE fans will know Vince as an active participant in the day-to-day running of the company. He regularly features on screen as a character protagonist in bouts.

But you may not know that Linda has also made a number of appearances.

There was the time she returned to save her daughter Stephanie McMahon from Sting, or when she stole a kiss with Eric Bischoff. She even got involved in an epic rumble between Vince and Shane McMahon, helping to change the course of the contest.

She was also once KOed by Stone Cold Steve Austin.

Does she have any qualifications?

Actually, yes.

You may turn up your nose at her WWE background, but as Mr Trump pointed out on Thursday, the McMahons have actually built a thriving business empire.

Ms McMahon "helped grow WWE from a modest 13-person operation to a publicly traded global enterprise with more than 800 employees in offices worldwide," Mr Trump said in a statement.

"Linda is going to be a phenomenal leader and champion for small businesses and unleash America's entrepreneurial spirit all across the country."

And although she may have failed in her two senate campaigns, in Connecticut in 2010 and 2012, at least it shows her interest in politics is nothing new, nor is her loyalty to the Republican Party.

Prior to her tilt at politics, Ms McMahon she was appointed to the Connecticut Board of Education, a post she gave up when she began campaigning.

Her role with the SBA will be to provide support to small business by extending loans and making sure they get a percentage of federal contracts.

We need to talk about Vince

Unlike some bosses, Vince McMahon is a constant presence on the shop floor at WWE.

You can probably tell from the rig on him that he is a retired wrestler himself, and he never hesitates to throw himself into WWE storylines.

Here are a couple of gifs of the man Ms McMahon has been married to for 50 years.

What's with Trump and WWE?

Has there ever been a President-elect appoint the spouse of someone who he once body-slammed and shaved bald? Don't bother answering that.

Mr Trump is obviously a WWE fan. He has featured in a raucous battle with Mr McMahon himself and is actually a WWE Hall of Fame member. We're not sure how one gets into the Hall of Fame.

Ms McMahon initially backed New Jersey Governor Chris Christie's bid for the White House, before coming around to Mr Trump's cause and donating $US6 million to a pro-Trump super PAC.

Numerous high-profile wrestlers threw their support behind Mr Trump during his campaign, including Kevin Nash, Jerry 'The King' Lawler and Hulk Hogan.
