It feels weird to see Zac Efron on the red carpet without his girlfriend and High School Musical co-star Vanessa Hudgens by his side.

Luckily, however, at the Australian premiere of Efron’s film, 17 Again, Taylor Swift was able to accompany the dreamy starlet. I’m not exactly sure why Taylor’s there–I don’t think she’s in the movie–but she is adorable, in her short, white dress.

As for Vanessa, she and Zac will have plenty of time to see one another again when they start filming for High School Musical 4. And 5 and 6 and 7 and…well, you get the idea.
