London, Nov 27 (IANS): Model Chrissy Teigen took baby son Miles for shopping after trolling her singer husband John Legend on Twitter for not spending enough time with his children.

The model engaged in a bit of lighthearted trolling on Twitter as her husband was trying to assure fans he would make all of his scheduled engagements over the holidays, reports dailymail.co.uk.

It kicked off when one fan tweeted her concern that the singer would cancel an upcoming show in Maryland, as he had apparently been double-booked for a tree lighting ceremony in New York that same night.

"Have no fear I'll be live in the flesh in Maryland on Wednesday," Legend assured her fan.

"I pre-taped my Rockefeller tree lighting performance on Thanksgiving Eve. See you soon!"

It was then Teigen chimed in uninvited, with a stinging: 'Hi - your kids."

The model showed him how it's done on Monday as she brought their six month-old son Miles out shopping with her.

The couple, who also share two-year-old daughter Luna, are no strangers to trading tongue-in-cheek barbs over social media.
