The acting career of pop stars is always a fascinating thing to watch. For every David Bowie who makes a long and lasting side-career out of appearances in credible films, there’s a Madonna, who occasionally flirts with movies but has mostly abandoned them now, or a Britney Spears who only tries it once and never really goes back.

Christina Aguilera is somewhere between those categories. The “Genie In A Bottle” songstress has a few credits to her name, but mostly as herself, in things like “Entourage” and “Get Him To The Greek,” with only Cher co-starring camp classic musical “Burlesque” as a true starring role. But she’s been making something of a comeback as a performer recently: she did a brief arc on “Nashville” in 2015, and will appear in Melissa McCarthy vehicle “Life Of The Party” in 2018. But her next gig might mark her biggest challenge to date: she’s teaming up with indie helmer Drake Doremus for his next picture.

A press release reveals that Aguilera has joined the cast of the sci-fi romance “Zoe,” along with “Divergent” actor Theo James, Rashida Jones, Miranda Otto and Matthew Gray Gubler, with Léa Seydoux and Ewan McGregor (who replaced the originally-cast Charlie Hunnam) still in the lead roles. Executive produced by Ridley Scott, the film tracks two colleagues at a research lab who are attempting to find a way to perfect romantic relationships.

We like Doremus, but he came a bit unstuck with his previous sci-fi/love story hybrid “Equals” — we hope this has a bit more meat on its bones, but the impressive cast certainly seems to suggest it might, and we’re intrigued to see what Aguilera brings to the party here.
