Beyonce supports Jay-Z at his '4:44' tour rehearsal

Aug. 24 (UPI) -- Beyoncé supported husband Jay-Z by attending his 4:44 tour rehearsal this week.

The 35-year-old singer showed off her stylish outfit Wednesday on Instagram as the 47-year-old rapper prepared for his upcoming fall tour.

Beyoncé posted a video featuring photos of her casual ensemble, sparkling jewelry and Jay-Z's rehearsal. She set the clip to Jay-Z's song Caught Their Eyes featuring Frank Ocean.

The Formation singer wore a white Stella McCartney t-shirt dress, a Virgil Abloh Off-White crossbody bag and a pink pair of 4:44 Puma sneakers. Her shoes read "1:44" -- the first of only 44 pairs made.

Jay-Z released 4:44 in June, and will kick off his accompanying tour Oct. 27 in Anaheim, Calif. The venture follows his and Beyoncé's move to Los Angeles, and the arrival of their twins, daughter Rumi and son Sir, in June. The couple also share 5-year-old daughter Blue Ivy.

"Beyoncé has been very busy with the newborns, but she's also been able to relax a bit," a source told People this week. "It's helped her that Blue has been such an amazing big sister."

"[Beyoncé has] made sure to spent lots of quality time [with Blue]," the insider added. "[Blue] takes her job as a big sister very seriously and helps out a lot."
