The 22-year-old actress has been taking her Cavalier King Charles spaniels on to the Rock Of Ages set, where co-star Cruise fell for the charms of the littlest one, Harley.
She told People magazine, 'Tom was telling me about [daughter] Suri and that she would probably love Harley.'
And she revealed that she can't bear to be parted from her precious pooches.
'They go everywhere with me,' she said. 'They are on set all the time, we take long walks. Adam Shankman, the director, has his two dogs there, too, so we've had a groomer come on set. It's pretty funny.'
'Being away from family and everything, it sometimes is tough. You go through your good days and your bad days,' she added. 'Having my dogs with me is literally my safe place. They're always there giving me joy and comfort and love.'
