They are yet to publicly confirm their relationship is back on.
But Katie Price's furious stare was definitely the look of a woman embroiled in a lovers tiff, rather than an annoyed friend.
The glamour model was spotted earlier this week jetting back from Prague with on/off boyfriend Leandro Penna after a romantic Valentine's Day getaway.
I'm sorry babe! Katie Price appeared to have gotten into an argument with her on/off boyfriend Leandro Penna at the airport in Prague after a romantic Valentine's Day getaway
Sources said she flashed an annoyed look at the Argentinian model as he grabbed her arm after the couple rowed at the airport on the way back to London.
An insider told The People: 'They couldn't get enough of each other in Prague but there was a row at the airport. When they got to Heathrow, Katie told Leandro to get a taxi and she went home in her pink Range Rover.'
But things were all peachy again yesterday, after Katie tweeted a picture of herself pigging out on junk food during a cosy night in with the hunk.
She was seen sporting a suspiciously large belly but before her fans jump to any baby-minded conclusions, the 33-year-old explained that her swollen stomach was the result of overindulging.

Katie tweeted: 'Omg @leandro__penna and @abbi1985 and myself have pigged out on junk food tonight hahahaha lol.'
She posed in the picture lounging on the couch, pushing her stomach out dramatically and surrounded by empty packets of chocolates and biscuits.
While the usually very public reality star has stopped short of confirming she is back with the Argentinian toyboy, Price has been seen out in public with Leandro on a number of occasions and has sent gushing tweets to him.

Penna wrote to his former girlfriend earlier this month: 'Your (sic) my perfect princess xx.'
In response Katie wrote, 'you are so gorgeous my perfect prince xx.'
Days later they were spotted sneaking out of a luxurious spa after spending the day there.
The pair reportedly broke up over the phone late last year, with a source telling the Sunday Mirror at the time: 'Katie knew in her heart that it was coming.
'She’s being very adult about the split and says she didn’t see it as a long-term relationship that would lead to marriage and kids.
