The 54-year-old director's New Beverly Cinema broke the news on Twitter, which Daniella confirmed to Ynet, according to The Hollywood Reporter.
Tarantino apparently met Daniella when he was in Israel to promote his 2009 film "Inglourious Basterds".
"It's true. We're very happy and excited," Pick told Ynetnews.Com of the engagement rumours.
The couple got engaged Friday night in LA.
Daniella is Israeli pop singer and composer Henrik Zvi "Svika" Pick's daughter.
