Jake Gyllenhaal's relationship with Alyssa Miller is reportedly getting serious.

The 'End of Watch' star, who recently started dating the Sports Illustrated beauty after splitting from swimsuit model Emily DiDonato, was spotted helping her move out of her apartment building on Wednesday (26.06.13), where she lived with her ex-boyfriend.

A source told the New York Post's Page Six that Alyssa, 23, and her former boyfriend, fashion photographer Bjorn Iooss Jr. moved into separate apartments in the same building after they split as they have remained on good terms but she decided to move out of the building completely this week and her doting new boyfriend was more than happy to assist her.

But the insider insisted that while Jake, 32, is smitten with the brunette model, he isn't ready to live with Alyssa just yet and she is still looking for a new place of her own.

She is believed to have put her belongings into storage and is staying with Jake and other friends in the meantime.

The 'Brokeback Mountain' actor has dated a slew of fellow A-list stars in the past including Reese Witherspoon, Kirsten Dunst, Minka Kelly and singer Taylor Swift.
