Megan Thee Stallion rehearses for Hot Girl Summer Tour in tiny red outfit... after her opening act GloRilla got arrested for DUI

Megan Thee Stallion worked up a sweat with her Hot Girl Summer Tour choreographer and back-up dancers in rehearsal on Thursday.

The 29-year-old hip-hop star showcased her fit 5ft10in figure while sporting a $42 red Nike 'Pro Dri-FIT' crop-top with matching $45 Nike 'Pro Dri-FIT' training shorts, red beanie, black Nike socks, and b&w sneakers.

'I just felt really good, because I knew exactly what colors I wanted. I knew exactly what the vibe was,' Megan said in her Adweek cover story last month.

'When I work out, I like to feel sexy. I like to feel confident. I like to feel like a little superhero. I like to feel snatched! The better you feel in your gym clothes, the harder you want to go.

'It keeps you motivated to keep coming back, because you want to see yourself look as good as you feel. With my collection, when I put it on, and hopefully when thee hotties put it on, they see themselves looking good, and it just pushes them to further their fitness goals.'

Stallion - who boasts 68.9M social media followers - performed a series of leg lift ab exercises on the floor.

The three-time Grammy winner captioned her Instastory video: 'Hot Girl Summer Tour loading!'

Megan - who gets 24.3M monthly listeners on Spotify - has already sold out 17 concerts of her 34-date tour, which kicks off May 14 at Target Center in Minneapolis, MN.

Stallion (born Megan Pete) was likely none too pleased to hear that her opening act and Wanna Be collaborator - GloRilla - was arrested in Georgia early Tuesday morning.

The 24-year-old Grammy-nominated rapper (born Gloria Hallelujah Woods) posted $1,956 bond after being charged by the Gwinnett County Sheriff's Office with suspicion of driving under the influence - according to TMZ.

On Wedensday, GloRilla called her arrest 'fake news' via Instastory by quoting Megan's new single Hiss: 'Y'all goofy a** ho** look so dumb / Every time y'all celebrate fake news, ha! / Using my name for likes and views / I don't give a f*** what y'all make trend, bi***, I still win!'

And on April 9, Stallion pre-taped an episode of ABC's Celebrity Family Feud, but it's unclear when season 10 of the game show will premiere.

'This might be in the top 5 of best family feud episodes,' the Texan native gushed on Instagram.

'I can't wait for y'all to see this!'
