On June 16, 2016, on the tenth anniversary of the series debut, Lonelygirl15 reappeared. The video has Bree reassuring an unnamed 15 year old subject about being selected, as Bree had been.

Rose reappeared as Bree on Lonelygirl15 in June 2016.

In March 2016, Rose became engaged to her partner and fellow actor Tim Phillipps. They married at the Royal Melbourne Yacht Squadron in early 2017.

In 2009, Rose appeared in the web series Poor Paul, which is produced by former lonelygirl15 co-star Yousef Abu-Taleb and the second season of the web series The Crew. Aside from acting, she is an Anaheim Ducks fan and periodically blogs for NHL.com.

On April 4, 2008, it was announced that she would star in a web television series called Blood Cell about "a young woman [who] must race against the clock to stop a sadistic madman after receiving a disturbing late-night phone call from a friend in danger." The series was released in October 2009 through theWB.com to little media fanfare. She also starred in another web series called Sorority Forever from Big Fantastic, the creators of Prom Queen. The series followed three incoming freshman in "the hottest sorority on campus" with some Gossip Girl and Veronica Mars elements to it. Additionally, she appeared in Hooking Up, a 10 episode web series from HBO featuring other recognized faces from the web including video bloggers sxePhil and KevJumba.

In November 2008, Rose teamed up with friend and fellow Sorority Forever star Taryn Southern to form a web production company called Webutantes, to potentially produce female-driven comedy web series. The two presented together at the 2009 Streamy Awards.

After leaving lonelygirl15 in August 2007, Rose played "Jen K." on ABC Family's Greek. She went on to appear in various movies, such as Perfect Sport and SyFy's Ghost Town, and other web series, such as Hooking Up and Sorority Forever. She signed on to do the independent movie Look at Me with her Lonelygirl15 co-star Yousef Abu Taleb in March 2010.

In August 2007, Rose landed a role on Greek as "Jen K.", Rusty Cartwright's girlfriend. On the show, her character referenced the actress's breakout role stating "It's like I'm living with lonelygirl15!" "Weeping Willow", a sixth season episode of the television series Law & Order: Criminal Intent, was inspired by the lonelygirl15 videos.

After her departure from lonelygirl15, Rose was signed by United Talent Agency and was cast in the ABC Family series Greek in the role of "Jen K" and the 2007 Chris Sivertson film I Know Who Killed Me, which starred Lindsay Lohan. She then played "Tina", an aspiring wrestler, in the award-winning sports drama Perfect Sport. In January 2009, Rose appeared in the music video for The White Tie Affair's song "Candle (Sick and Tired)," and the following October, she appeared in the Syfy television movie, Ghost Town.

The lonelygirl15 video blogs, which first appeared in mid-2006, featured Rose as a 16-year-old girl named Bree posting under the alias lonelygirl15. The videos, which seemed genuine and presented lonelygirl15 as an actual person, initially dealt with typical teenage angst issues but soon after introduced a bizarre narrative surrounding secret occult practices within her family. The series was an immediate hit and became the most subscribed channel on YouTube but suspicions arose as to whether the videos were genuine or some sort of a promotional gimmick.

An investigation by the Los Angeles Times would reveal the lonelygirl15 videos as a work of fiction. A firestorm ensued in the news media through September 2006 during which Jessica Rose and the creators of lonelygirl15 gained international attention and were interviewed by various magazines and television shows. In October 2006, the United Nations chose Rose via her character Bree to participate in an ad campaign to promote the UN's antipoverty cause.

After Rose's parents separated, she returned to Salisbury in May 2005 to live with her father. She then enrolled in the New York Film Academy (NYFA) at Universal Studios in Universal City, California. In her search for acting jobs, she found a listing for an independent film project The Children of Anchor Cove on Craigslist. She auditioned for the lead part and was offered the role of Bree. Rose signed a non-disclosure agreement and was told that the project would consist of a series of videos released to the World Wide Web over the Internet. The idea concerned her at first, as she was afraid the project was pornography, but she was convinced otherwise and agreed to partake. Although initially unpaid, as lonelygirl15 grew popular, she and co-star Yousef Abu-Taleb received salaries.

Rose was born in Salisbury, Maryland, and moved to Mount Maunganui, Bay of Plenty, New Zealand when she was eight. She attended Mount Maunganui College in 2000–2003 for part of her secondary school education. Afterward she attended an acting class at Studio 111 in Auckland. In January 2004, she moved to Auckland to study at the Academy of Film and Television Make Up.

Jessica Lee Rose (born April 26, 1987) is an American-New Zealand actress who first gained popularity after playing the role of lonelygirl15, a fictional teenage homeschooled character named Bree who appeared in YouTube video blogs, beginning in June 2006. The mystery surrounding the possible fictionality of her character led to an outing by the Los Angeles Times, which thrust her into the mainstream spotlight. In 2007, Rose won a Webby for this role.
