Jennifer Aniston believes beau Jim Curtis is her 'kismet'

Jennifer Aniston is very happy in her relationship with Jim Curtis, says an insider.

The 'Friends' star is excited to spend quality time with her beau ahead of the holiday season and is looking forward to decorating her house.

“The holidays are when [Aniston] slows down, truly enjoys her house and spends time with the people she loves,” the source tells PEOPLE.

“She’s very happy to be spending it with Jim this year,” the insider added, explaining that Aniston “loves this time of year,” and “always goes all-in for Christmas.”

“She has a real tree every year — never artificial,” the source continued. “She loves decorating her house to make it feel warm and festive.”

Earlier, a source told the People magazine that the Morning Show actress and Curtis spent, "months chatting and getting to know each other" at the start of the year.

"Jen really valued their friendship in the beginning of the year," the insider said. "When it all took a turn to something more romantic, she was cautious at first. Now, she's excited that she just went for it."

The tipster added that it "feels like kismet" and that the Aniston “truly loves" Curtis. "He's brought so many good things into her life," adds the source.

The couple confirmed their relationship in November as they went Instagram official on Curtis 50th birthday.

Few days later the love birds made their first public appearance together at ELLE’s Women in Hollywood event, where Aniston described Curtis as “quite extraordinary" in an interview with the outlet.

She said, “He’s very special, very normal, and very kind, and wants to help people heal, move through their trauma and stagnation into clarity."

Although the couple is delighted to announce their relationship, Aniston’s cautious approach seemingly came due to experiencing intense media scrutiny during her past high-profile relationships.
