Jennifer Aniston and Justin Theroux attended Christie's "Artists for Haiti" auction in New York on Thursday, where the actress dropped $450,000 on a painting.
Theroux did the bidding for his leading lady, who clapped enthusiastically after winning artist Glenn Ligon's oil, charcoal and graphite abstract painting, "Stranger #44," according to ArtInfo.com.
The 6 foot tall painting, which can be seen below, was completed in 2011 and was estimated to go for between $150,000 and $200,000.
Artists donated their work for the "Artists for Haiti" auction, which was co-organized by Ben Stiller and raised $13,662,000 for the organization which benefits health and education in Haiti.
According to Us Weekly, Aniston and Theroux spent time with Stiller and his wife Christine Taylor after the auction, catching a late dinner at New York's Il Cantinori.
Stiller appeared opposite Aniston in "Along Came Polly" and co-wrote "Tropic Thunder" with Theroux and the couple recently took a romantic trip to Hawaii, where they helped actor Ben Stiller and his wife Christine Taylor celebrate Taylor's 40th birthday at the couple's oceanfront home.
The couple has reportedly been house-hunting since July, but have been living in a two-bedroom Hollywood Hills rental house since August 1, while they keep looking for the perfect home.
The actress moved out of her Beverly Hills home in July after deciding she needed to "simplify" her life. The property sold for $38 million.
Aniston, 42, and Theroux, 39, have been romantically linked since May. Photographer Terry Richardson recently gave fans a glimpse of the happy couple snuggling in New York.
Aniston will next appear opposite Paul Rudd in the comedy "Wanderlust," about an urban couple who leaves the city to try a counter-culture lifestyle. Theroux also stars in the film, which is slated for release on October 7, 2011.
