Stay away, boys! Brian Austin Green chaperones Megan Fox to new film set after revelations of Transformers fling

Brian Austin Green certainly made his presence felt as he chaperoned his wife Megan Fox to her first day of work on The Dictator today. 

The former Beverly Hills 90210 stuck right by the actress' side as he escorted her onto the New York City set of The Dictator this morning.

It seems Green may be feeling a little over-protective following revelations Fox sparked up a romance with co-star Shia LaBeouf while filming Transformers. 

United front: Megan Fox and Brian Austin Green prove they're together and happier than ever on the New York City set of her new comedy The Dictator this morning

For her part, Fox looked low-key in a blue v-neck T-shirt, black leggings, a baseball cap and trainers.

This is the second time in a week that the couple has been photographed together; on July 7 they strolled hand-in-hand through the streets of Santa Monica, California, looking happy and in love.

If LaBeof's admission rattled their relationship, they certainly weren't letting it show on either occasion. 

It's a bird, it's a plane: Megan and her man hang out in the Big Apple

Under her umbrella: The 25-year-old actress really IS a shady lady!

LaBeof told Details magazine earlier this month: 'Look, you're on the set for six months, with someone who's rooting to be attracted to you, and you're rooting to be attracted to them.' 

He refused to say whether or not the starlet was with Green at the time.

He said: 'I don't know, man. I don't know. I don't know. I don't know...It was what it was.'

Fox and Green had an on-again off-again romance for years before finally marrying in 2010. 

Keep it covered: Megan was surrounded by her entourage and Brian who held an umbrella over her head

Low profile: Megan seemed to be keeping her head down first with a cap and later by simply putting her head down 

The star, who was sacked from the Transformers franchise, is now hoping to resuscitate her once red-hot career withThe Dictator.

The film, which stars Sacha Baron Cohen and Anna Faris, is being directed by Larry Charles who helmed Bruno and Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan and certain to be hilarious. 

Additionally, Megan is also starring in Friends With Kids alongside Bridesmaids alums Kristen Wiig, Maya Rudloph and Jon Hamm as well as Knocked Up director Judd Apatow's yet-to-be-titled project. 

Happy go-lucky: The starlet isn't going to let any rumours dog her: she's going to grin and bear it!

Together forever? The brunette beauty and her husband made their first public outing since Shia LaBeouf revealed he hooked up with his Transformers co-star on 7 July in Santa Monica, California
