She revealed on Instagram on Thursday that Maureen has been staying with her during the lockdown while paying tribute to her pal who she affectionately refers to as ‘Mosie’.

‘On my good days, people ask if we’re sisters, but more often than I care to admit—the assumption is mother/daughter. We aren’t actually related —but I’ll claim her.’ Jennifer began her post.

The actress credited Maureen for helping her stay organized and being her travel buddy, as well as helping her with her Instagram content.

‘People ask what social media company I use—well, I sit in the excellent company of @mogrosser, noodling on ideas, and edits, and captions, playing to our morphed-into-one funny bone.

She ended the gushing tribute writing, ‘Mo isn’t one to want attention, but she’s in lockup with me at my crazy house and it’s her birthday. Plus it’s time I post something without her approval, for crying out loud. Happy birthday, Mosie, we are lucky to have you here with us, today and always. We love you.’
