John Legend and Chrissy Teigen have been praised after hiring several food trucks in New York City to feed homeless people in the city and those who are protesting over the police killings of Eric Garner and Michael Brown.

The 'All of Me' hitmaker and his model wife were reportedly behind the rental of several food trucks which turned up in New York City and gave out hundreds of meals to those who are protesting over the police killings of Eric Garner and Michael Brown, as well as the homeless.

News aggregator Bipartisan Report posted a picture of two of the vans on Twitter and added the caption: ''BREAKING: #johnlegend pays for a food truck in Lincoln sq to feed #EricGarner supporters before the #NYC protest. (sic)'' Activism organisation Operation Help or Hush also alerted people to news of the trucks, which included one serving gourmet macaroni cheese and another offering tacos.

A post on its Twitter account read: ''3-6pm. FREE food trucks by Trader Joe's Union Sq. @ophelporhush #FergusontoNYC #NYC2Ferguson (sic)'' The message was later retweeted by Chrissy, 29, although she and John, 35, are yet to accept responsibility for the free food trucks.

Following the generosity, several people took to the social networking site to thank the couple - who tied the knot last year - for their kindness.

One wrote: ''I can now publicly THANK @chrissyteigen & johnlegend 4 GENEROUSLY funding today's @ophelporhush 'family dinner' #FergusontoNYC #NYC2Ferguson (sic)'' Another posted: ''@akacharleswade @chrissyteigen @ophelporhush that is *amazing* of them! Good to see humanity coming together! (sic)''
