Gwyneth Paltrow isn't the only A-lister to dabble in Airbnb, with Ashton Kutcher and Mila Kunis now opening up their beachfront Southern California guesthome for one night only. 

The couple are allowing one lucky family-of-four the opportunity to stay with them at their Santa Barbara beach house for free. Kutcher, 45, and Kunis, 40, have been known to frequent the guesthouse for family fun with their two children, Wyatt and Dimitri - and hope the special getaway will help "foster connection" between them and their guests.

From 5am (NZDT) on August 17, families can request to book the stars' beach house for Saturday, August 19 (PST) for a grand total of $0. Meanwhile, Airbnb has pledged a one-time donation to Thorn, an international anti-human trafficking organisation founded by Kutcher and his ex-wife Demi Moore to fight against the sexual exploitation of children.

The one-night stay will include an itinerary curated by the couple, which includes joining the two for some of their favourite family pastimes: think hiking nearby trails, a trip to the beach, visiting the local shops and restaurants, taking in the panromantic coastal views, and a cosy night in playing board games and charades.

Earlier this month, Goop founder and actor Gwyneth Paltrow partnered with Airbnb to offer her Montecito guesthouse for one night on Saturday, September 9, promising the "ultimate retreat" with an itinerary curated by Paltrow herself. Activities for the stay include a guided session of transcendental meditation, a spa day featuring Paltrow's favourite products, a nourishing meal and a selection of Goop goodies to take home. 

Those hoping to secure the special overnight retreat with Paltrow can request to book now, with requests opening at 5am this morning.
